摘要：

The polymeric ruthenium(I) complex [Ru-2(CO)(4)(mu -OAc)(2)](n) is a Suitable catalyst for the cyclopropanation of mono-, 1,1- as well as 1,2-disubstituted, and trisubstituted alkenes with (trimethylsilyl)diazomethane, phenyl-diazomethane. and (4-cyanophenyl)diazomethane. Trisubstituted alkenes are cyclopropanated with a remarkable degree of syn-selectivity. (C) 2001 Elsevier Science Ltd. All rights reserved.
