Abstract

Abstract Vilsmeier formylation of vinylcyclopropanes 1 (cC 3 H 5 CR 1 [DOUBLE BOND] CHR 2, R 1= alkyl, cycloalkyl, phenyl and vinyl, R 2= hydrogen and alkyl), affords the corresponding 3-cyclopropylacroleïns in excellent yields (75-95%). Vinylcyclopropanes without an α-substituent (R 1= H) react very sluggishly and give poor yields (10-20%) with the exception of the parent compound, vinylcyclopropane (65%), and ...
