Abstract
A one-pot regioselective allene hydrosilylation/Pd(0)-catalyzed cross-coupling protocol affords functionalized 1,1-disubstituted alkenes with excellent regiocontrol. The regioselectivity of this hydroarylation is primarily governed by N-heterocyclic carbene (NHC) ligand identity in the hydrosilylation step and is preserved in the subsequent cross-coupling reaction.
