Abstract Three-component carboboration of alkenes takes place efficiently by the reaction with a diboron compound and carbon electrophiles with the aid of a copper–NHC catalyst. The carboboration afforded diverse multisubstituted borylalkanes via the regioselective formation of carbon–boron and carbon–carbon bonds. Three-component carboboration of alkenes takes place efficiently by the reaction with
electronically unbiased alkenes has been developed, providing straightforward access to secondary aliphatic boronicesters from readily available materials under very mild reaction conditions. The regioselectivity of this reaction is governed by a unique pyridyl carboxamide ligated catalyst, rather than the substrates. Moreover, this transformation shows excellent chemo‐ and regio‐selectivity and remarkably
