This article demonstrates a catalytic method for C(aryl)—C(alkyl) bond functionalization of N-sulfonyl amines. A cobalt(III) catalyst was used to cleave the C—C bond via β-carbon elimination, providing a metallacycle intermediate. Subsequent allylation, amidation, or alkenylation of the intermediate led to divergent conversions in the presence of diverse coupling partners. when the coupling partner
本文展示了一种催化N-磺酰胺 C(芳基)-C(烷基)键功能化的方法。钴 (III) 催化剂用于通过 β -碳消除裂解 C-C 键,提供金属环中间体。随后中间体的烯丙基化、酰胺化或烯基化导致在存在不同偶联伙伴的情况下发生不同的转化。当偶联配偶体是二烯时,插入型功能化实现了具有独有的 1,3-区域选择性,其中使用了衍生自N-磺酰胺的两个片段。
