A chemo- and regioselective 1,2-carboboration of arylallenes by alkenylboranes, formed in situ by hydroboration of alkynes with Piers’ borane (HB(C6F5)2) is reported. This novel 1,2-carboboration and a subsequent Suzuki-Miyaura coupling were used for the synthesis of twenty new aryl substituted 1,4-dienes.
报道了通过炔烃与 Piers 硼烷 (HB(C 6 F 5 ) 2 )原位氢化形成的烯基硼烷对芳基丙二烯进行化学和区域选择性1,2-碳硼化反应。这种新颖的 1,2-碳硼化和随后的 Suzuki-Miyaura 偶联被用于合成 20 种新的芳基取代的 1,4-二烯。
