| Abstract: | Reactions of [{Ru(n6-C10H14)Cl2}2] (n6-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(n6-C1-H14)Cl2}2(m-CNPy)] and the mononuclear complex [Ru(n6-C1-H14)Cl2(CNPy)].The latter complex further reacts with [{Ru(n6-C6Me6)Cl2}2] and [Ru(n5-
C5H5)(PPh3)2Cl] to give 4-cyanopyridine bridged complexes [Cl2(n6-C1-H14)Ru(m-CNPy)Ru(n6-C6Me6)Cl2] and [Cl2(n6-
C1-H14)Ru(m-CNPy)Ru(n5-C5H5)(PPh3)2].The complex [Ru(n6-C1-H14)Cl2(CNPy)] also undergoes metathetical reactions with
EPh3 (E-P, As or Sb) to give complexes with the general formulations [Ru(n6-C1-H14)Cl2(EPh3)], however its reaction with
diphenylphosphinomethane (dppm) in a 1:1 ratio gives the mononuclear complex [Ru(n6-C10H14)Cl2(dppm)] in which the dppm
ligand is present in uncommon coordination mode (n1-dppm). The reaction products have been characterized by microanalyses
and spectroscopic studies (IR, 1H-, 13C-, 31P... |
