Abstract
Reaction of cyclopropylacylsilanes with sulfuric or triflic acid in ap rotic solvent affords the corresponding cyclobutanone or 2-silyl-4,5-d ihydrofuran derivatives, depending upon the substituents on the three- membered ring or acid used. The use of triflic acid results in the sel ective formation of the dihydrofurans.
