:Bulky electron-withdrawing groups can cause the vinylogous portion of the vinylcarbenoid to become the active electrophilic site, but usually the use of nonpolar solvents can minimize this type of reactivity.

Vinylogous — reactivity is the behavior of a vinyl group in conjugation with an electron withdrawing group analogous to the reactions of the electron withdrawing group itself; typically, this is a carbonyl group. Vinylogous reactions are found when the pi… … Wikipedia
