Abstract

Since the original preparation of diphenylcyclopropenone by Breslow3 and Vol'pin4 in 1959, the syntheses and reactions of a wide variety of cyclopropenones have been studied for many years. 5 Remarkably, however, there have been only a few references to the syntheses of alkoxy-substituted cyclopropenones, and these suffer from very poor yields and/or multistep procedures. 6-8 Although a fairly general approach to 3-aryl-2- ...
