A bridged two-vial system aminocarbonylation protocol where Mo(CO)6 functions as an external in situ solid source of CO has been developed. For the first time both nitro group containing aryl/heteroaryl iodides and bromides gave good to excellent yields in the Mo(CO)6-mediated and palladium(0)-catalyzed conversion to benzamides, while the identical one-vessel protocol afforded extensive reduction of
已开发了桥接的两瓶系统氨基羰基化方案,其中Mo(CO)6用作外部原位CO固体源。含硝基的芳基/杂芳基碘化物和溴化物都首次在Mo(CO)6介导的和钯(0)催化的转化为苯甲酰胺的过程中获得了优异的优异收率,而相同的单容器实验方案则大大降低了硝基功能。上述桥连的两室方案在65–85°C反应温度下对伯胺和仲胺以及迟钝的苯胺亲核试剂均提供了良好的结果。
