A wide range of polyfunctional aryl, heteroaryl, alkyl, and benzylic zinc reagents were coupled with unsaturated aryl halides bearing an acidic NH or OH proton, usingpalladium(II) acetate (1 mol%), and S-Phos (2 mol%) as catalyst without the need of protecting groups. palladium catalysis - cross-coupling - functionalized zinc reagents - polyfunctional biaryls
