Abstract
The polymeric ruthenium(I) complex [Ru-2(CO)(4)(mu -OAc)(2)](n) is a Suitab
le catalyst for the cyclopropanation of mono-, 1,1- as well as 1,2-disubsti
tuted, 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 Elsev
