Abstract
Cu-catalyzed formal hydroboration of terminal or 1,1-disubstituted alkenes with bis(pinacolato)diboron and methanol provides products with exceptional regiocontrol favoring the branched isomer. Subsequent photocatalytic cross-couplings using iridium and nickel cocatalysis enable a highly regioselective hydroarylation of terminal alkenes.
