Abstract
B-H bond activation: Depending on the stability of the borane adduct, Li/Cl carbenoids react with BH3⋅LB either under B-H bond activation at the carbenic carbon center or under carbene dimerization. The B-H bond activation proceeds in a stepwise fashion with the nucleophilic attack of the Li/Cl carbenoid at BH3⋅LB as the crucial step determining the course of the reaction.
摘要
B-H键活化：根据硼烷加合物的稳定性，Li/Cl类卡宾与BH₃⋅LB的反应，要么在类卡宾碳中心发生B-H键活化，要么发生卡宾二聚反应。B-H键活化以逐步方式进行，其中Li/Cl类卡宾对BH₃⋅LB的亲核进攻是决定反应进程的关键步骤。
