ipso-borylation of aryl sulfides with diboron reagents has been achieved, providing arylboronate esters of synthetic use. The key conditions to transform inherently reluctant C–S bonds into C–B bonds include a palladium-NHC (N-heterocyclic carbene) precatalyst, bis(pinacolato)diboron, and lithium hexamethyldisilazide. This protocol is applicable to a reasonable range of aryl alkyl sulfides. Twofold borylation
一种催化宫浦型本位与二硼试剂芳基硫化物的-borylation已经实现,从而提供合成的使用arylboronate酯。将本来就不愿意的C–S键转换为C–B键的关键条件包括钯-NHC(N-杂环卡宾)预催化剂,双(频哪醇)二硼和六甲基二硅叠氮化锂。该协议适用于合理范围的芳基烷基硫化物。在二苯硫醚的反应中观察到双重硼化。
