Carbanions containing leaving groups react in the presence of base with electrophilicalkenes giving products in which vinylic hydrogen is replaced with the carbanion moiety. They are formed via addition - β-elimination pathway analogous to the vicarious nucleophilicsubstitution in nitroarenes. In some cases, however, the cyclization - ring opening process takes place instead.
