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, using palladium(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
使用乙酸钯(II)(1 mol%)和S-Phos(2 mol%)将多种多官能芳基,杂芳基,烷基和苄基锌试剂与带有酸性NH或OH质子的不饱和芳基卤化物偶联作为催化剂,不需要保护基。 钯催化-交叉偶联-功能化锌试剂-多官能联芳基
