Two new aminophosphines - furfuryl-(N-dicyclohexylphosphino)amine, [Cy 2PNHCH2-C4H3O] (1) and thiophene-(N-dicyclohexylphosphino)amine, [Cy2PNHCH 2-C4H3S] (2) - were prepared by the reaction of chlorodicyclohexylphosphine with furfurylamine and thiophene-2-methylamine. Reaction of the aminophosphines with [Ru(η6-p-cymene)(μ-Cl)Cl] 2 or [Ru(η6-benzene)(μ-Cl)Cl]2 gave corresponding complexes [Ru(Cy2PNHCH2-C4H 3O)(η6-p-cymene)Cl2] (1a), [Ru(Cy 2PNHCH2-C4H3O)(η6- benzene)Cl2] (1b), [Ru(Cy2PNHCH2-C 4H3S)(η6-p-cymene)Cl2] (2a) and [Ru(Cy2PNHCH2-C4H3S) (η6-benzene)Cl2] (2b), respectively, which are suitable catalyst precursors for the transfer hydrogenation of ketones. In particular, [Ru(Cy2PNHCH2-C4H 3S)(η6-benzene)Cl2] acts as a good catalyst, giving the corresponding alcohols in 98-99% yield in 30 min at 82 °C (up to time of flight ≤ 588 h-1).
