An organobase-catalyzed 1,1-diborylation of terminal alkynes from propargylic derivatives with bis(2,4-dimethylpentane-2,4-glycolato)diboron (B2oct2) is first reported, regioselectively providing 1,1-diborylalkene products with high efficiency. The catalytic pathway is well postulated on the basis of DFT calculations.
首次报道了用双(2,4-二甲基戊烷-2,4-乙醇酸)二硼(B 2 oct 2)对来自炔丙基衍生物的末端炔烃进行有机碱催化的 1,1-二硼基化反应,区域选择性地提供 1,1-二硼基烯烃产物高效率。在 DFT 计算的基础上很好地假设了催化途径。
