摘要：
A mononuclear Ru(II) eN-heterocyclic carbene (NHC) complex [Ru-II(CO)2(k(2)C, N-BIN)(H2O)Br][OTf] (OTf trifluoromethane sulphonate) (1) has been synthesized in high-yield by the oxidative cleavage of the metal-metal singly-bonded diruthenium(I) precursor [Ru-2(CO)(4)(CH3CN)(6)(OTf)(2)] with 1,8-naphthyridine functionalized NHC precursor 1-benzyl-3-(5,7-dimethyl-1,8-naphthyrid-2-yl) imidazolium bromide (BIN center dot HBr) at room temperature. Compound 1 catalyzes transfer hydrogenation of ketones to alcohols, and carbene-transfer from ethyl diazoacetate to a variety of substrates. It is shown to be an excellent catalyst for the insertion of carbene into the O-H and N-H bonds of alcohols and amines. (C) 2010 Elsevier B.V. All rights reserved.
