Activated by DBU, N-haloimides can be used as both halogen and nitrogen sources to achieve the difunctionalization of terminal alkynes, giving rise to useful halogenated enamines with high efficiency and high regio- and stereoselectivities. The cascade reaction features simple manipulation, mild conditions, a broad substrate scope, readily available reagents, and atom-economy.
在 DBU 的激活作用下，N-卤代酰亚胺既可用作卤素源，也可用作氮源，从而高效高区域和立体选择性地实现末端炔烃的双官能化，得到有用的卤化烯胺。该级联反应具有操作简单、条件温和、底物范围广、试剂易得和原子经济性等特点。
