  • Patent number: 6258967
    Abstract: A process for the preparation of an aromatic organozinc compound is provided. The process comprises reacting a zinc chloride, bromide or iodide and an organometallic compound of another metal comprising an aromatic moiety, producing a reaction product comprising an organozinc compound and a halide salt of the other metal. The reaction product is then contacted with a liquid hydrocarbon, in which the organozinc compound is soluble and the halide salt of the other metal is of low solubility. The halide salt of the other metal is separated from the hydrocarbon, and the organozinc compound can be recovered from the hydrocarbon. Organozinc compounds produced by this process can be employed to generate chiral centres in suitable substrates.
