An organobase-catalyzed 1,1-diborylation of terminal alkynes from propargylic derivatives with bis(2,4-dimethylpentane-2,4-glycolato)diboron (Boct) is first reported, regioselectively providing 1,1-diborylalkene products with high efficiency. The catalytic pathway is well postulated on the basis of DFT calculations.
首次报道了一种有机碱催化的炔丙基衍生物末端炔烃与双（2,4-二甲基戊烷-2,4-二醇酸根）二硼（Boct）的1,1-二硼化反应，该反应区域选择性地高效提供1,1-二硼基烯烃产物。基于密度泛函理论计算，对催化途径进行了合理推测。
