Reactions of ω-diphenylphosphino-functionalized alkyl phenyl sulfides Ph(2)P(CH(2))(n)SPh (n=1, L1; 2, L2; 3, L3), sulfoxides Ph(2)P(CH(2))(n)S(O)Ph (n=1, L4; 2, L5; 3, L6) and sulfones Ph(2)P(CH(2))(n)S(O)(2)Ph (n=1, L7; 2, L8; 3, L9) with the dinuclear chlorido bridged ruthenium(II) complex [{Ru(η(6)-p-cymene)Cl(2)}(2)] afforded mononuclear

An easily accessible in situ catalyst composed of [{RuCl(2)(p-cymene)}(2)] and terpyridine has been developed for the selective transfer hydrogenation of aromatic nitro and azo compounds. The procedure is general and the selectivity of the catalyst has been demonstrated by applying

Asymmetric transfer hydrogenation (ATH) of cyclic imines using [RuCl(η(6)-p-cymene)TsDPEN] (TsDPEN = N-tosyl-1,2-diphenylethylenediamine) was tested with various aliphatic (secondary, tertiary) and aromatic amines employed in the HCOOH-base hydrogen donor mixture. Significant differences in reaction rates and stereoselectivity were observed, which pointed

The ruthenium(II) carboxylate complex [Ru(O(2)CMes)(2)(p-cymene)] enabled efficient direct arylations of unactivated C-H bonds with easily available, inexpensive phenols. Extraordinary chemoselectivity of the well-defined ruthenium catalyst set the stage for challenging C-H/C-O bond functionalizations to occur under solvent-free conditions as well

Complex [(p-cymene)Ru(η(1)-O(2)CCF(3))(2)(OH(2))] mediated transformation of α-diazoacetamides ArCH(2)N(C(CH(3))(3))C(O)CHN(2) to result in carbene insertion into the primary C-H bond exclusively, with the γ-lactam products being isolated in up to 98% yield. This unexpected reaction is striking in view of the presence of
