摘要：

The cationic complex [Ru(salen)(NO)H2O]SbF6 is intrinsically a powerful catalyst for the Mukaiyama crossed-aldol reaction at 25-degrees-C in nitromethane solutions and at very low catalyst loadings but, for some reactions. electron transfer from the silyl enol ether to the ruthenium catalyst can occur which leads to catalyst deactivation.
