Abstract
The polymeric ruthenium (I) complex [Ru2 (CO) 4 (μ-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.
