The syntheses and characterization of a series of cationic of Ru(II) halfsandwich complexes of the types [Ru(eta(6)-p-cymene)(kappa(2)(P,N)-PN)Cl](+) (PN =N-diphenylphosphino-2-aminopyridine, N-di-iso-propylphosphino-2-aminopyridine, 2-[(2-pyridyl)amino]dibenzo[d,f][1,2,3]dioxaphosphepine, N-(diisopropylphosphino)-2,6-diaminopyridine) and [Ru(eta(6)-p-cymene)(kappa(2)(E,N)-EN)Cl](+) (EN = N-(2-pyridinyl)amino-diphenylphosphine sulfide, N-(2-pyridinyl)amino-diisopropylphosphine sulfide, N-(2-pyridinyl)amino-diphenylphosphine selenide, N-(2-pyridinyl)amino-diisopropylphosphine selenide) is described. Some of these complexes were tested as precatalysts for the transfer hydrogenation of acetophenone to give 1-phenyl ethanol. (C) 2010 Elsevier Ltd. All rights reserved.
