摘要：

Vinyl type carbocations ArC+=CHX [X = CO2H, CO(2)Alk, C N, P(O)(OAlk) 2] generated from alkyl 3-arylpropynoates and related compounds in fluorosulfonic acid at -75 to -20 degrees C react with various benzene derivatives, following the mechanism of electrophilic substitution of hydrogen. A new procedure for the synthesis of alkyl 3,3-diarylpropenoates having various substituents in the aryl fragments has been developed on the basis of protonation of the triple bond in alkyl 3-arylpropynoates.
