摘要

Abstract A variety of substituted cyclopropenone ketals have been prepared by electrophilic trapping (protonolysis and alkylation) of sodium salts of cyclopropenone ketals that have been generated directly from the ketals of 1, 3-dichloroacetone derivatives through cyclization with NaNH 2 in a liq. NH 3/ether mixture.
