Reactions of alkynylborate salts, easily derived from reaction of frustrated Lewis pairs with terminal alkynes, with diazonium salts to induce 1,1-carboboration affording a facile and efficient route to substituted electrophilic vinyl boranes.
炔基硼酸盐与重氮盐的反应很容易从沮丧的路易斯对与末端炔烃反应中衍生出来,与重氮盐诱导1,1-碳硼化反应,从而为取代的亲电子乙烯基硼烷提供了一种简便而有效的途径。
