Catalytic Addition-Elimination Reactions Towards Butenolides

Abstract

A wide range of selenium-containing reagents are known to undergo addition – elimination reactions under different reaction conditions. We report on selenium electrophiles, which are regenerated under the reaction conditions employed, and therefore only catalytic amounts of these reagents are necessary.
