A controllable diastereoselectiveC(sp2)-C(sp3) Negishi coupling reaction of secondary benzylic zinc reagents with aryl bromides has been demonstrated for the first time, forming medicinally important 1-arylphenylethylamines. In the presence of Pd(OAc)2 and S-phos, open-chain (2–amido-1-phenylethyl)zinc reagents bearing a β-NHAc or NHCHO group underwent cross-couplingreaction to give syn 1-arylphenylethylamine
