We have examined the reaction of cyclopropylcarbene-chromiumcomplexes with alkenes. The reaction leads to the formation of cyclopropylcyclopropane derivatives in good yield, accompanied by minor amounts of ring-opened products. Conjugated dienes and α,β-unsaturated esters and amides appear to be suitable substrates for the reaction.

The reaction of cyclopropylcarbene-chromium complexes with alkenes has been examined. The reaction leads to cyclopropylcyclopropane derivatives in good yield, accompanied by minor amounts of ring-opened products. Conjugated dienes and alpha,beta-unsaturated esters and amides appear to be suitable substrates for the reaction. The products of the reaction are donor-acceptor substituted cyclopropanes and are further susceptible to transformations typical of this class of compounds.
