Abstract

Abstract On treating potassium salts of n-membered cyclic keto esters or sulfones with phenyl 1-propenyl selenone, a one-carbon ring expansion reaction involving cyclopropanation or vinylation takes place to give the corresponding bicyclo [(n-1). 1.0] alkanones or (n+ 1)-membered cyclic ketones bearing vinyl group at their 3-position.
