Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 37366-09-9, C12H12Cl4Ru2.

(4S)-4-Isopropyl-2-(3-nitrophenyl)-4,5-dihydrooxazole ((S)-Phox) is introduced as a novel chiral auxiliary for the asymmetric synthesis of ruthenium polypyridyl complexes. A simply accessible (S)-Phox-bearing precursor serves as the starting point for diastereoselective coordination chemistry: The stereogenic carbon atom of the cyclometalating auxiliary controls the spatial arrangement of incoming 1,10-phenanthrolines during ligand substitution reactions (ratio Lambda:Delta up to 14:1), and further precipitation affords diastereopure compounds. In the following key step, the labilization of the auxiliary ligand is achieved by reduction, thus permitting its replacement against a third polypyridyl ligand with complete retention of the configuration at the metal center (er > 99:1) under mildly acidic conditions, in contrast with previously developed systems that require strong acid. On the basis of results of NMR experiments and X-ray analysis obtained for intermediate compounds, mechanistic considerations for the formation of diastereomeric complexes were made, revealing a Delta ? Lambda isomerization as the reason for the observed limitations in selectivity optimization. This work expands the pool of methods available for the asymmetric synthesis of tris-heteroleptic ruthenium polypyridyl complexes and additionally may serve as an inspiration for the synthesis of other nonracemic octahedral chiral-at-metal compounds.

Combining chemistry: The use of a lipase and a ruthenium catalyst allows the direct preparation of polysubstituted decalines with high optical and chemical yields from racemic alcohols (see scheme). The lipase-catalyzed kinetic resolution of the racemic alcohols, the ruthenium-catalyzed racemization of the slow-reacting enantiomers, and an intramolecular Diels-Alder reaction of the resultant esters all occur under identical conditions.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2.

Treatment of 4-(2?-pyridyl)dibenzothiophene (PyDBT) with the ruthenium carbonyl cluster [Ru3(CO)12] gave the diruthenium(II) complex [Ru(mu-PyBPT-kappa3TV, CS)(CO) 2]2 (1), where PyBPT denotes a dianion of 3?-(2?-pyridyl)-1,1?-biphenyl-2-thiol. The tridentate-N,C,S PyBPT ligand provides a pincer structure consisting of a six-membered thiaruthenacycle and a five-membered azaruthenacycle. The thiolatecontaining NCS pincer ligand in 1 is produced by cleavage of a carbon-sulfur bond adjacent to a pyridyl group in PyDBT. The corresponding reactions using 4-(4?-methyl- 2?-pyridyl)dibenzothiophene (4-MePyDBT) and 4-(6?-methyl-2?- pyridyl)dibenzothiophene (6-MePyDBT) afforded the diruthenium(II) complexes with the same pincer framework [Ru(mu-4-MePyBPT-kappa3N, C, S)(CO)2]2 (2) and [Ru(mu-6-MePyBPT-k3N, C, S)(CO)2J2 (3), respectively. The much slower formation of 3 certifies the reaction path through the initial coordination of the pyridyl group to Ru or the formation of an N,S-chelate structure. Indeed, PyDBT showed the chelating ability in the ruthenium(II) complex [Ru(eta6-C 6H6)(PyDBT-kappa2N,S)Cl]CF3SO 3 (4). Complex 1 contains Ci and C2 symmetrical isomers, 1a and 1b, respectively, which were separated. The latter isomerized to la in DMSO-d6 at 80 C. The stepwise formation of the same NCS pincer ligand was established in the reaction of [Rh(mu-Cl)(CO) 2]2 with PyDBT. The facile reaction at room temperature produced the mononuclear rhodium(I) complex cis-[RhCl(CO)2(eta 1 -N-PyDBT)] (5). The isolated complex 5 was converted to the tetranuclear rhodium(I/III/III/I) complex [ {Rh(mu-PyBPT-kappa3N, C,5)}(-Cl)2{Rh(CO)2}]2 (6) at 100 C for 3 days.

The ruthenium(II) triazenido complex [RuCl(ClC6H 4N3C6H4Cl)(p-cymene)] (1) is obtained by the reaction of silver bis(p-chlorphenyl)triazenid with [RuCl 2(p-cymene)]2 in CH2Cl2, and forms air stable, orange yellow crystals. It crystallizes as 1·CH 2Cl2 in the orthorhombic space group Pbca with the lattice parameters a = 3134.3(3), b = 2105.7(2), c = 769.15(4) pm and Z = 8. In the diamagnetic mononuclear complex 1 the chelating triazenido ligand coordinates with the atoms N(1) and N(3). p-Cymene binds eta6 with its C 6 ring. The reaction of the etherphosphane complex [RuCl 2(Ph2PCH2C4H7O 2)2] with 1,3-bis(p-tolyl)triazenid in THF yields the complex [RuCl(tolyl-N3-tolyl)(Ph2PCH2C 4H7O2)2] (2). 2 forms monoclinic, red crystals with the space group P21/c and a = 1521.0(2), b = 1451.8(2), c = 2073.7(2) pm, beta = 99.29(1) and Z = 4. It is air stable and diamagnetic. The triazenide ion coordinates with the atoms N(1) and N(3). One of the two etherphosphane ligands is chelating and coordinates with the P atom and one O atom, while the other ligand binds in a monodentate fashion with its P atom, resulting in a coordination number of six for the RuII. [Ag(tolyl-N5-tolyl)]2 reacts in THF with [RuCl 2(C6H6)]2 to afford the air stable, diamagnetic pentaazadienido complex [RuCl(tolyl-N5-tolyl)(C 6H6)] (3). 3 forms monoclinic, red crystals with the space group P21/c and a = 1462.4(1), b = 1056.51(8), c = 1371.4(1) pm, beta = 114.36(1) and Z = 4. The chelating pentaazadienido ligand coordinates with the atoms N(1) and N(3) at the divalent Ru atom. The benzene molecule binds eta6 with its pi system.

Neutral and cationic mononuclear complexes containing both group 15 and polypyridyl ligands [Ru(kappa3-tptz)(PPh3)-Cl 2] [1; tptz = 2,4,6-tris(2-pyridyl)-1,3,5-thazine], [Ru(kappa3-tptz)(kappa2-dppm)CI]BF4 [2; dppm = bis(diphenylphosphino)-methane], [Ru(kappa3-tptz)(PPh 3)(pa)]Cl (3; pa = phenylalanine), [Ru(kappa3-tptz) (PPh3)(dtc)]Cl (4; dtc = diethyldithiocarbamate), [Ru(kappa3-tptz)(PPh3)(SCN)2] (5) and [Ru(kappa3-tptz)(PPh3)(N3)2] (6) have been synthesized. Complex 1 has been used as a metalloligand in the synthesis of homo- and heterodinuclear complexes [Cl2(PPh 3)Ru(mu-tptz)Ru-(eta6-C6H 6)Cl]BF4 (7), [Cl2(PPh3)Ru(mu- tptz)Ru(eta6-C10H14)Cl]PF6 (8), and [Cl2(PPh3)Ru(mu-tptz)Rh(eta5-C 5Me5)Cl]BF4 (9). Complexes 7-9 present examples of homo- and heterodinuclear complexes in which a typical organometallic moiety [(eta6-C6H6)RuCl]+, [(eta6-C10H14)RuCl]+, or [(eta5-C5Me5)RhCl]+ is bonded to a ruthenium(II) polypyridine moiety. The complexes have been fully characterized by elemental analyses, fast-atom-bombardment mass spectroscopy, NMR ( 1H and 31P), and electronic spectral studies. Molecular structures of 1-3, 8, and 9 have been determined by single-crystal X-ray diffraction analyses. Complex 1 functions as a good precursor in the synthesis of other ruthenium-(II) complexes and as a metalloligand. All of the complexes under study exhibit inhibitory effects on the Topoisomerase II-DNA activity of filarial parasite Setaria cervi and beta-hematin/hemozoin formation in the presence of Plasmodium yoelii lysate.

The ruthenaborane anions [Ru3(CO)9BH4]- and [Ru3(CO)9B2H5]- can be used as building blocks to assemble tetraruthenium butterfly clusters incorporating a wingtip Ru(eta6-Ar) fragment in place of the isolobal Ru(CO)3 fragment present in the previously reported compound [Ru4H(CO)12BH2]. The syntheses and spectroscopic characterizations of [Ru4H(eta6-Ar)CO)9BH2] (Ar = C6H6, C6H5Me, MeC6H4-4-CHMe2) are reported. A single crystal structure determination of [Ru4H(eta6-C6H5Me)(CO)9BH2] confirms the location of the eta6-arene ligand in a wingtip site but reveals that the butterfly framework is essentially unperturbed in going from an Ru(CO)3 to Ru(eta6-Ar) cluster fragment.

The catalytic hydrogenation of various benzene derivatives was studied, using (eta6-C6H6)2Ru2Cl4 in aqueous solution as the catalyst precursor. Under biphasic conditions, the corresponding cyclohexane derivatives are obtained with catalytic turnover rates which vary, depending on the substrate, from 20 to 2000 cycles per h. After a catalytic run, the aqueous solution contains the two tetranuclear cations [(eta6-C6H6)4Ru4H4]2+ and [(eta6-C6H6)4Ru4H6]2+ which are known to catalyse the hydrogenation of aromatic compounds, but the activity of which is considerably lower than that of the (eta6-C6H6)2Ru2Cl4 precursor. An intermediate, presumably the more active species, was detected by 1H-NMR spectroscopy under catalytic conditions and identified as the trinuclear cluster cation [Ru3(eta6-C6H6)3(mu2-Cl)(mu3-O)(mu2-H)2]+.

The reaction of <(Ru(eta6-C6H6)Cl2)2> with the sodium salt of (S)-N-(1-phenylethyl)salicylideneamine (HL-L) in CH2Cl2 led to a diastereomer mixture of (RRu,SC)- and (SRu,SC)- 1a and 1b, in a ratio of 86:14.Mediated by AgPF6 in acetone at -30 to -35 deg C, the chloride ligand in 1a/1b was substituted by 4-methylpyridine (4Me-py), 2-methylpyridine (2Me-py) or triphenylphosphane (PPh3) to give the two diastereomers 2a/2b of PF6, the pure diastereomer 3 of PF6 and the two diastereomers 4a/4b of PF6.At room temperature in <(2)H6>acetone, under equilibrium conditions, the diastereomer ratio 2a:2b was 67:33, 3 was diastereomerically pure and the ratio 4a:4b was 93.4:6.6.Variable-temperature 1H NMR spectroscopy of complexes 2a/2b and 4a/4b from -80 deg C to room temperature demonstrated configurational lability of the ruthenium configuration.Since equilibration occured during reaction and work-up, the ruthenium configuration was not retained in the substitution reactions.Diastereomer 2a was obtained diastereomerically pure by crystallisation.The diastereomers 4a and 4b were separated and examined by variable-temperature NMR spectroscopy.The crystal structures of the (RRu,SC) diastereomer of complex 1 and of the thermodynamically more stable (RRu,SC) diastereomers 2a and 4a” were determined by X-ray analysis.A conformational analysis based on the NMR spectroscopic results showed that two main factors govern the orientation of the 1-phenylethyl group relative to the moiety (L’=Cl, 4Me-py, 2Me-py or PPh3): (i) the face-on orientation of the phenyl substituent with respect to the ?-bonded aromatic benzene ligand and (ii) the steric demand of the unidentate ligands with respect to the 1-phenylethyl group.
