Gold(I)-catalyzed cross-couplingreactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium
描述了金(I)催化的芳基重氮盐与有机锡烷的交叉偶联反应。这种氧化还原中性策略为各种联芳基,乙烯基芳烃和芳基乙炔提供了一种有效的方法。用NMR和ESI-MS监测反应为原位形成Ph 3 PAu I R(R =芳基,乙烯基和炔基)物种提供了有力证据,这对于激活芳基重氮盐至关重要。
