The X-ray crystal structure determination of [RuCp(mTPPMS)(PPh3)-(PTA)]·2H2O (8·2H 2O), which is the first half-sandwich ruthenium complex bearing three different phosphanes, has also been determined. The binding properties of these new water-soluble ruthenium complexes towards DNA and the interaction of free mTPPMS with the nucleic acid have been studied using the mobility shift assay, which has shown that both the activity of the ruthenium complexes and the possible mechanism governing the interaction with DNA are strictly dependent on the composition of the complexes.

The hydrides RuH2(C5H6)(Pcy3)2 (2) and RuH(C5H5)(Pcy3)2 (3) (cy = cyclohexyl) are formed in the reaction of RuH6(Pcy3)2 (1) with cyclopentene, although in the presence of 3,3-dimethylbut-1-ene only (3) is formed quantitatively, but treatment of (1) with C5Me5H gives no C5Me5 complex (although in C6D6 active H-D exchange with the phosphine protons is observed); however n when treated with phosphine (L = PMe3, PPh3, P(i-Pr)3, or Pcy3) gives the paramagnetic complexes RuCl2(C5Me5)L, which on treatment with LiBHEt3 in tetrahydrofuran yields the new trihydrides RuH3(C5Me5)L.

In this paper we report the reaction of [Ru(eta5-C5H5)Cl(PPh3)2] with P{CH2N(CH2CH2)2O}3 in the presence of NaBF4, in which, apart from the Cl- substitution, an unexpected P-C bond cleavage in the tertiary phosphane is observed. It results in the formation of [Ru(eta5-C5H5)(PH{CH2N(CH2CH2)2O}2)(PPh3)2]BF4 (1) – the first “piano-stool” ruthenium complex with a secondary aminomethylphosphane ligand.

The products were alkenylethynyl complexes (from aprotic nucleophiles) or methylallenylidene complexes (from protic nucleophiles, with H migration to C6).

The reaction of 2-guanidinobenzimidazole (GBI) and (eta5-C5H5)Ru(PPh3)2(Cl) in refluxing toluene gives the chelate [(eta5-C5H5)Ru(PPh3)(GBI)]+Cl- (1+Cl-; 96%). Subsequent anion metatheses yield the BF4-, PF6-, and BArf- (B(3,5-C6H3(CF3)2)4-) salts (77-85%). Reactions with CO give the carbonyl complexes [(eta5-C5H5)Ru(CO)(GBI)]+X- (2+X-; X- = Cl-, BF4-, PF6-, BArf-; 87-92%). The last three salts can also be obtained by anion metatheses of 2+Cl- (77-87%), as can one with the chiral enantiopure anion P(o-C6Cl4O2)3- ((delta)-TRISPHAT-; 81%). The reaction of [(eta5-C5H5)Ru(CO)(NCCH3)2]+PF6- and GBI also gives 2+PF6- (81%). The pentamethylcyclopentadienyl analogues [(eta5-C5Me5)Ru(CO)(GBI)]+X- (3+X-; X- = Cl-, BF4-, PF6-, BArf-; 61-84%) are prepared from (eta5-C5Me5)Ru(PPh3)2(Cl), GBI, and CO followed (for the last three) by anion metatheses. An indenyl complex [(eta5-C9H7)Ru(PPh3)(GBI)]+Cl- (96%) is prepared from (eta5-C9H7)Ru(PPh3)2(Cl) and GBI. All complexes are characterized by NMR (1H, 13C, 31P, 19F, 11B), with 2D spectra aiding assignments. Crystal structures of 1+PF6-·CH2Cl2 and 1+BArf-·CH2Cl2 are determined; the anion is hydrogen bonded to the cation in the former. Complexes 1-3+X- are evaluated as catalysts (10 mol %, RT) for condensations of indoles and trans-beta-nitrostyrene. The chloride salts are ineffective (0-5% yields, 48-60 h), but the BArf- salts exhibit excellent reactivities (97-46% yields, 1-48 h), with the BF4- and PF6- salts intermediate. Evidence for hydrogen bonding of the nitro group to the GBI ligand is presented. GBI shows no catalytic activity; a BArf- salt of methylated GBI is active, but much less so than 2-3+BArf-.

Ligand substitution of [(Ind)Ru(PPh3)2Cl] (1) led to the isolation of [(Ind)Ru(PPh3)(Ph2P(CH2) 2C9H7}Cl] (2), [(Ind)Ru(dppf)Cl] (3) and [(Ind)Ru{(Ph2PCH2)3CMe}]PF6 ([4]PF6), and diastereoisomers [(R)- and (S)-(Ind)Ru(Josiphos)Cl] [(R)-5 and (S)-5], where (R)-(S)-Josiphos is the ferrocene-based chiral diphosphane ligand (R)-(-)-1-[(S)-2-(diphenylphosphanyl)ferrocenyl] ethyldicyclohexylphosphane. The Cp analogues of 5, viz. (R)-6 and (S)-6, were also obtained from [CpRu(PPh3)2Cl] (1a). Josiphos-dependent epimerisation was observed, with conversion of the (S) isomer to the (R) isomer in both cases. Chloride abstraction of 3 with NaPF 6 in CH3CN and NaN3 in EtOH gave [(Ind)Ru(dppf)(CH3CN)]PF6 ([7]PF6) and [(Ind)Ru(dppf)(N3)] (8), respectively. The azido ligand in 8 underwent [3+2] dipolar cycloaddition with dimethyl acetylenedicarboxylate to give a N-bound bis-(methoxycarbonyl)-1,2,3-triazolato complex, 9. X-ray crystal structures of the new complexes, except (R)-5, (S)-5 and (S)-6, have been determined. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Reactions of 3,6-bis(2-pyridyl)-4-phenylpyridazine (Lph) with [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p-iPrC6H4Me and C6Me6), [(eta5-C5Me5)M(mu-Cl)Cl]2, (M = Rh and Ir) and [(eta5-Cp)Ru(PPh3)2Cl] (Cp = C5H5, C5Me5 and C9H7) afford mononuclear complexes of the type [(eta6-arene)Ru(Lph)Cl]PF6, [(eta5-C5Me5)M(Lph)Cl]PF6 and [(Cp)Ru(Lph)(PPh3)]PF6 with different structural motifs depending on the pi-acidity of the ligand, electronic properties of the central metal atom and nature of the co-ligands. Complexes [(eta6-C6H6)Ru(Lph)Cl]PF6 1, [(eta6-p-iPrC6H4Me)Ru(Lph)Cl]PF6 2, [(eta5-C5Me5)Ir(Lph)Cl]PF6 5, [(eta5-Cp)Ru(PPh3)(Lph)]PF6, (Cp = C5H5, 6; C5Me5, 7; C9H7, 8) show the type-A binding mode (see text), while complexes [(eta6-C6Me6)Ru(Lph)Cl]PF6 3 and [(eta5-C5Me5)Rh(Lph)Cl]PF6 4 show the type-B binding mode (see text). These differences reflect the more electron-rich character of the [(eta6-C6Me6)Ru(mu-Cl)Cl]2 and [(eta5-C5Me5)Rh(mu-Cl)Cl]2 complexes compared to the other starting precursor complexes. Binding modes of the ligand Lph are determined by 1H NMR spectroscopy, single-crystal X-ray analysis as well as evidence obtained from the solid-state structures and corroborated by density functional theory calculations. From the systems studied here, it is concluded that the electron density on the central metal atom of these complexes plays an important role in deciding the ligand binding sites.

Herein, we have formulated the concept of systematic derivatization of a structural motif via C-H bond functionalization. This concept may not only serve as a blueprint for new strategies in diversity synthesis but also provide systematic guidance for the identification of unsolved and important synthetic challenges. To illustrate this point, 2-phenylimidazole was selected as the core motif for this study, a choice inspired by numerous azole-based synthetics, including pharmaceuticals (compound SB 202190), and also fluorescent and chemiluminescent probes. We were able to show that systematic and comprehensive arylation of the 2-phenylimidazole core was feasible, and in the context of this study new arylation methods were developed. The direct 4-arylation of free 2-phenylimidazole was achieved with iodoarenes as the aryl donors in the presence of palladium catalyst (Pd/Ph3P) and magnesium oxide as the base. A complete switch from C-4 to C-2? arylation was accomplished using a ruthenium catalyst [CpRu(Ph3P)2Cl] and CS 2CO3. The corresponding transformations for (N,2)-diphenylimidazole (C-5 and C-2? arylation) were accomplished via the palladium-based method [Pd(OAc)2/Ph3P/CS 2CO3] and a rhodium-catalyzed procedure [Rh(acac)(CO) 2/CS2CO3], respectively. All of the arylation methods described herein demonstrated broad synthetic scope, high efficiency, and exclusive selectivity. Furthermore, these new methods proved to be orthogonal to one another and applicable to sequential arylation schemes. With these methods in hand, arrays of arylated imidazoles may now be accessed in a direct manner from 2-phenylimidazole. This strategy stands in sharp contrast to a traditional approach, wherein a distinct and multistep synthesis would be required for each analogue.
