Study of half-sandwich platinum group metal complexes bearing dpt-NH2 ligand

A quite general approach for the preparation of eta5-and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, C10H14 and C6Me6) and eta5-pentamethylcyclopentadienyl rhodium and iridium complexes [(eta6-C5Me5)M(mu-Cl)Cl]2 (M = Rh, Ir) react with 2 equiv. of 4-amino-3,5-di-pyridyltriazole (dpt-NH2) in presence of NH4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(dpt-NH2)Cl]PF6 {arene = C10H14 (1), C6H6 (2) and C6Me6 (3)} and [(eta6-C5Me5)M(dpt-NH2)Cl]PF6 {M = Rh (4), Ir (5)}. However, the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3)2Cl], [(eta5-C5H5)Os(PPh3)2Br], [(eta5-C5Me5)Ru(PPh3)2Cl] and [(eta5-C9H7)Ru(PPh3)2Cl] complexes react in presence of 1 equiv. of dpt-NH2 and 1 equiv. of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(dpt-NH2)]PF6 (6), [(eta5-C5H5)Os(PPh3)(dpt-NH2)]PF6 (7), [(eta5-C5Me5)Ru(PPh3)(dpt-NH2)]PF6 (8) and [(eta5-C9H7)Ru(PPh3)(dpt-NH2)]PF6 (9), respectively. These compounds have been totally characterized by IR, NMR and mass spectrometry. The molecular structures of 4 and 6 have been established by single crystal X-ray diffraction and some of the representative complexes have also been studied by UV-Vis spectroscopy.

Reactions of [{Ru(eta6-C10H14)Cl2}2] (eta6-C10H14=p-cymene H3C-C6H4-CH(CH3)2) with 4-cyanopyridine (referred hereafler as CNPy) in 1:1 and 1:2 molar ratios in dichloromethane yields the binuclear complex [{Ru(eta6-C10H14)Cl2} 2(mu-CNPy)] and the mononuclear complex [Ru(eta6-C10H14)Cl2(CNPy)]. The latter complex further reacts with [{Ru(eta6-C6Me6)Cl2}2] and [Ru(eta5-C5H5)(PPh3) 2Cl] to give 4-cyanopyridine bridged complexes [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(mu6-C6Me 6)Cl2] and [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(eta5-C5H 5)(PPh3)2]+. The complex [Ru(eta6-C10H14)Cl2(CNPy)] also undergoes metathetical reactions with EPh3 (E=P, As or Sb) to give complexes with the general formulations [Ru(eta6-C10H14)Cl2(EPh 3)], however its reaction with diphenylphosphinomethane (dppm) in a 1:1 ratio gives the mononuclear complex [Ru(eta6-C10H14)Cl2(dppm)] in which the dppm ligand is present in uncommon coordination mode (eta1-dppm). The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H-, 13C-, 31P-NMR). The structure of [Ru(eta6-C10H14)Cl2(CNPy)] [a=10.984(1), b=14.052(1), c=12.189(1) A; beta=114.810(1); V=1707.8(4) A3; Dcalc=1.596 g cm-3; monoclinic P21/c; Z=4] and confirmation of uncommon coordination mode of dppm, in [Ru(eta6-C10H14)Cl2(dppm)] [a=11.504(3), b=19.532(3), c=15.942(3) A; beta=96.08(2); V=3562(2) A3; Dcalc=1.446 g cm-3; monoclinic P21/n; Z=4] has been determined by X-ray crystallography.

The redox properties of a series of cyclopentadienylruthenium compounds, (eta5-C5H5)Ru(PPh3)(L)X (L = PPh3, pyridine; X = H, Cl) and (eta5-C5H5)Ru2Cl,have been studied in different nonaqueous solvents (MeCN, THF, CH2Cl2).The ruthenium(II)/ruthenium(III) couple is observed in the potential range of +0.05 V to +0.70 V (vs SCE) depending upon the type of ligands and the solvent medium.The E0298 values vary in the order THF > CH2Cl2 > MeCN.While the couple is nearly reversible in MeCN, the electron transfer is sluggish (i.e., quasireversible) in other solvents.The E0298 values follow the order: (eta-Cp)Ru-2Cl > (eta-Cp)Ru(PPh3)(py)Cl <* >(eta-Cp)Ru(PPh3)2Cl > (eta-Cp)Ru(PPh3)2H(eta-Cp = eta5-C5H5).

Ru(II)-catalyzed cycloadditions of 1,6-heptadiynes with alkenes: New synthetic potential of ruthenacyclopentatrienes as biscarbenoids in tandem cyclopropanation of bicycloalkenes and heteroatom-assisted cyclocotrimerization of 1,6-heptadiynes with heterocyclic alkenes

The ruthenium(II)-catalyzed tandem cycloaddition of 1,6-heptadiynes with bicyclic alkenes, such as bicyclo[3.2.1]heptenones and norbornene derivatives, furnishes the 1:2 adducts between the diynes and two molecules of the bicycloalkenes together with common [2 + 2 + 2] cyclocotrimerization products. The structure of a representative tandem 1:2 adduct between dimethyl dipropargylmalonate and 2,4-dimethylbicyclo[3.2.1]-oct-6-en-3-one was unequivocally determined by X-ray analysis and was concluded to involve an unusual 1,2-dicyclopropylcyclopentene skeleton. On the basis of the spectroscopic analogy, the previously communicated structures of the tandem cycloadducts between the diynes and norbornene derivatives were corrected. The formation of the tandem double-cyclopropanation products from the diynes is chemical evidence of a biscarbenoid hybrid structure, 1,3,5- metallacyclopentatriene, of the corresponding 2,4-metallacyclopentadiene intermediates. The selectivity for the formation of the tandem cyclopropanation adducts was increased in the order of (eta5- C9H7)Ru(PPh3)2Cl > CpRu(cod)Cl > Cp*Ru(cod)Cl, indicative of the eta5 ? eta3 ring slippage of the cyclopentadienyl type ligands playing a key role in the tandem cyclopropanation. On the other hand, the normal [2 + 2 + 2] cyclocotrimerization between 1,6-heptadiynes and alkenes was selectively catalyzed by Cp*Ru(cod)Cl, in the case of cyclic or linear alkenes possessing heteroatoms at the allylic position. The latter heteroatom- assisted cyclocotrimerization was also catalyzed by a paramagnetic dinuclear ruthenium(III) complex, [Cp*RuCl2]2, at lower temperature.

Cyclopentadienyl ruthenium complexes. Part III. Reactivity of some eta5-cyclopentadienylbis(triphenylphosphine)ruthenium(II) complexes with nitrosyl tribromide and dinitrogen trioxide

Mixed ruthenium(II) nitrosyls have been synthesized in yields larger than 60percent by a general reaction of +X- (L = 2,2′-bipyridine or 1,10-phenanthroline, X- = Cl- or Br-) or (L = PPh3, pyridine, 3-picoline, 4-picoline, 1/2(2,2′-bipyridine), or 1/2(1,10-phenanthroline); X- = Cl-, Br-, I-, CN-, NCS-, H-, or SnCl3-) with NOBr3 and N2O3.In these complexes NO seems to bind with the metal ion as NO+.The reactions of N2O3 gave either nitrito or nitrosyl dinitrito complexes.The reactions of NOBr3 with trichlorostannate complexes did not yield nitrosyl complexes, instead nitrito complexes were isolated in which spectroscopic evidence (ir, 1H nmr) suggest ?-interaction of one of the phenyl rings of the triphenylphosphine ligand to the ruthenium center.All products are characterised by elementary microanalyses, conductivity, magnetic moment measurements, electronic, ir, 1H nmr spectral data.

Discovery of Cell-Permeable O-GlcNAc Transferase Inhibitors via Tethering in Situ Click Chemistry

O-GlcNAc transferase (OGT) is a key enzyme involved in dynamic O-GlcNAcylation of nuclear and cytoplasmic proteins similar to phosphorylation. Discovery of cell-permeable OGT inhibitors is significant to clarify the function and regulatory mechanism of O-GlcNAcylation. This will establish the foundation for the development of therapeutic drugs for relevant diseases. Here, we report two cell-permeable OGT inhibitors (APNT and APBT), developed from low-activity precursors (IC50 > 1 mM) via ?tethering in situ click chemistry (TISCC)?. Both of them were able to inhibit O-GlcNAcylation in cells without significant effects on cell viability. Unusual noncompetitive inhibition of OGT was helpful to discover novel inhibitors and explore the regulatory mechanism of OGT. The development of these molecules validates that TISCC can be utilized to discover novel lead compounds from components that exhibited very weak binding to the target.
