摘要

The hetero-Michael reactions among various oxygen, sulfur, and nitrogen nucleophiles and α,β-unsaturated compounds were carried out in the presence of catalytic amounts of o-benzenedisulfonimide as Brønsted acid organocatalyst. The reaction conditions were very mild, and the yields of target products were good. The catalyst was easily recovered and purified, ready to be used in further reactions. This ability grants economic and ecological advantages.
