Abstract

Arenediazonium salts generated in situ from anilines have been found for the first time to efficiently oxidize [AuCl(L)] (L = SMe2, PPh3) complexes in DMSO as a solvent, under thermal conditions. The structure of the [AuArCl2(L)] complexes formed has been confirmed by X-ray diffraction analyses. These complexes have been used as intermediates, in a one pot cross-coupling reaction of anilines with silver acetylides.

摘要

首次发现，由苯胺原位生成的芳基重氮盐在热条件下能在二甲基亚砜（DMSO）溶剂中高效氧化[AuCl(L)]（L = SMe₂、PPh₃）配合物。通过X射线衍射分析确定了所形成的[AuArCl₂(L)]配合物的结构。这些配合物已被用作中间体，用于苯胺与乙炔银的一锅法交叉偶联反应。
