摘要

本研究描述了一种在温和条件下由钯催化的邻碘芳基烯与磺酸钠的高效多米诺偶联反应。这种新方法提供了一种实用的方案，通过在一锅中同时构建 C（sp2）-C（sp2）键和 C（sp3）-S 键来获得各种含吲哚和苯并呋喃的砜。这种转化方法的突出特点是操作简单、底物范围广、官能团耐受性好。

Synthesis of Indole- and Benzofuran-Based Benzylic Sulfones by Palladium-Catalyzed Sulfonylation of ortho-Iodoaryl Allenes.

A highly efficient palladium-catalyzed domino coupling reaction of ortho-iodoaryl allene with sodium sulfonates under mild conditions is described. This novel method provides a practical protocol to access diverse indole- and benzofuran-containing sulfones by simultaneous construction of C(sp²)-C(sp²) bond and a C(sp³)-S bonds in one pot. The salient features of this transformation include simple operations, broad substrate scope, and good functional group tolerance.
