Continuing efforts to establish a more general âuser-friendlyâ protocol for the palladium-catalysed arylation of amines (BuchwaldâHartwig reaction) are described herein. Significant advances have been made through the use of the versatile (SIPr)Pd(methallyl)Cl complex in conjunction with the reliable base lithium hexamethyldisilazide (LHMDS).
本文描述了持续努力建立一种更为通用的“用户友好”协议,以实现钯催化的芳基化胺反应(Buchwald–Hartwig反应)。通过使用多功能的(SIPr)Pd(methallyl)Cl配合可靠的碱性氢六甲基二硅氮(MHMDS),已取得显著进展。
