an efficient mechanochemical strategy for chemo‐, regio‐ and stereo‐selective oxidative Heck coupling of readily accessible arylboron reagents/heteroaromatics with unactivated cyclic and acyclic olefins. Mono‐ and bis‐arylation were achieved without the need of ligands, directing groups or prefunctionalized alkenes, and the reaction chemo‐selectivity could be controlled by tuning of the oxidative system
在这项工作中,我们提出了一种易于化学的,化学的,区域性的和立体选择的氧化性Heck偶联的有效机械化学策略,该偶联易于使用的芳基硼试剂/杂芳族化合物与未活化的环状和无环烯烃。单芳基化和双芳基化无需配体,直接基团或预官能化的烯烃即可实现,反应化学选择性可通过调节氧化系统来控制。该方案可在宽范围的底物范围内提供烯基苯的合成,令人满意的收率和优异的选择性(即使以克为单位)。
