The radical deboronative cyanation of alkyltrifluoroborates with a broad range of functional groups is enabled by visible-light photoredox catalysis.
A Cu2O nanoparticle catalyzed borylation of alkylboronic esters is developed, with mild reaction conditions, high yield and in the absence of ligands which otherwise are essential in homogenous catalysis, using bis(pinacolato)diboron as the boron source.
