An easy to operate method of catalytic hydroboration of unsaturated compounds has been developed with wide substrate scope. Reactions of various aldimines, ketimines, α,β-unsaturated carbonyl compounds, and alkynes were successfully executed with bis(pinacolato)diboron and N-heterocyclic carbenes in methanol without requiring a transition metal or inert atmosphere.
一种易于操作的催化氢硼化不饱和化合物的方法已经开发出来,适用范围广泛。各种醛亚胺、酮亚胺、α,β-不饱和羰基化合物和炔烃的反应已成功在无过渡金属或惰性气氛的条件下,使用双(pinacolato)二硼和N-杂环卡宾在甲醇中进行。
