Abstract: 1-Ethenylcyclopropyl sulfonate underwent electrophilic γ- and α-substitutions by the carbonyls of naturally occurring biphenyls derived from vanillin and acetovanillone, in the presence of palladium(0) and diethylzinc, to provide regioisomeric 5,5-di(3-cyclopropylidene-1-hydroxypropyl) biphenyls and 5,5-di[1-(1-ethenylcyclopropyl)-1-hydroxymethyl]biphenyls of biological interest.
