The reaction of functionalized primary alkyl bromides with Et2Zn in DMPU in the presence of a catalytic mixed metal system constituted of MnBr2 (or FeCl3) and CuCl provides functionalyzed alkylzinc bromides (> 80 % yield). In the presence of PdCl2(dppf) or CuCN·2LiCl, these organozinc species reach with a range of electrophiles providing various polyfunctional molecules in good yields.
