Abstract

Abstract: The cycloaddition reactions of the monoalkylallenes ethyl-, isopropyl-, and tert- butylallene and the dialkylallene 1, l-dimethylallene with diethyl fumarate (DEF) and maleate (DEM) have been investigated. The comparison of the chemoand stereoselectivities observed in these reactions with those observed in the cycloaddition reactions with 1, l- dichloro-2, 2-difluoroethene indicates that the reactions with DEF and DEM occur via two- ...
