Article abstract of DOI:10.1021/ja00040a006

Cyclopropenone acetals bearing olefinic substituents of diverse electronic character have been synthesized and examined for their thermal behavior toward water and electron-deficient olefins. The substituted cyclopropenes underwent regio- and stereoselect
