摘要：

Pentacarbonyl(methoxystyrylcarbene)-chromium(0) reacts with sulfur ylides to yield cyclopropanes and vinyl ethers derived from the competitive 1,4- vs 1,2-addition of the nucleophile to the alpha,beta-unsaturated complex. Phosphorus ylides give 1,2-addition exclusively, while nitrogen ylides do not react with the above complex.
