Hypervalent iodine catalysis has been widely utilized in olefin functionalization reactions. Intermolecularly, the regioselective addition of two distinct nucleophiles across the olefin is a challenging process in hypervalent iodine catalysis. We introduce here a unique strategy using simple lithium salts for hypervalent iodine catalyst activation. The activated hypervalent iodine catalyst allows the intermolecular coupling of soft nucleophiles such as amides onto electronically activated olefins with high regioselectivity.
高价碘催化已广泛应用于烯烃官能化反应中。在分子间,通过烯烃进行两种不同亲核试剂的区域选择性加成是高价碘催化中一个具有挑战性的过程。我们在此介绍一种使用简单锂盐来活化高价碘催化剂的独特策略。活化后的高价碘催化剂能够使诸如酰胺等软亲核试剂与电子活化烯烃进行分子间偶联,并具有高区域选择性。
