2,3-Dihydroboroles are readily formed by treatment of dicyclopropylacetylene with the strongly electrophilic borane B(C6F5)3. The reaction involves a sequence of 1,1-carboboration reactions and proceeds via dienylborane intermediates. Consistent with this, the reaction of the conjugated enyne 15c with B(C6F5)3 leads to the formation of a dihydroborole.
通过用强亲电性硼烷B(C 6 F 5)3处理二环丙基乙炔,很容易形成2,3-二氢硼烷。该反应包括1,1-碳硼化反应的序列,并通过二烯基硼烷中间体进行。与此相一致,共轭烯炔15c与B(C 6 F 5)3的反应导致二氢硼烷的形成。
