An easy to operate method of catalytic hydroboration unsaturated compounds has been developed with wide substrate scope. Reactions various aldimines, ketimines, α,β-unsaturated carbonyl compounds, and alkynes were successfully executed bis(pinacolato)diboron N-heterocyclic carbenes in methanol without requiring a transition metal or inert atmosphere.
