Deprotonation of pinacol trimethylsilylmethaneboronate yields an anion which reacts with carbonyl compounds to form alkeneboronic esters, or with alkyl halides to form α-trimethylsilylalkaneboronic esters.

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
