A palladium-catalyzed silyl-Negishi reaction between secondary zinc organometallics and silicon electrophiles provides direct access to alkyl silanes. The balance of steric and electronic parameters of the employed DrewPhos ligand suppresses isomerization and promotes efficient and selective cross-coupling.
