Pd(OAc)2 is an efficient catalyst precursor for Negishi coupling in the presence of Bu4NBr. Secondary and primary alkylzinc reagents with β-H and arylzinc reagents all reacted with aryl iodides at low temperatures in good yields. Preliminary kinetic studies indicated that the process involved the formation of Pd-nanoparticles as the active catalytic species.
