sequence of reactions. The over all result is the insertion of a functionalized 2-carbon unit between the original olefinic carbons. The efficiency of the method is demonstrated by a high-yield synthesis of ,-muscone.

allyl tributyltin, introduces an exo-oriented side chain on the ring. Sequential hydrohalogenation and free radical ring expansion of cyclobutanones gives, three- carbon, ring-expanded, cis-fused cycloheptanones.
