Methylmanganese pentacarbonyl-mediated transformation of enynes to cyclopropanated bicyclic compounds and cyclopentanes bearing an exocyclic double bond has been carried out. Control of the product distribution can be achieved by changing reaction conditi
REACTIONS OF ENYNES WITH ADSORBED METAL-CARBENES

Adsorbed on silica-gel or on other adsorbants (MgSO4, Na2SO4, or Na2CO3), but not in homogeneous solution, pentacarbonyl(methoxyethylidene)chromium combines with simple enynes to give bicyclohexanes.The method's usefulness is illustrated by the synthesis of a variaty of previously unknown structures from simple hydrocarbons, ethers, and amines.
