PROCESS FOR THE IN SITU ACTIVATION OF ZINC METAL

摘要

The present invention provides a non-carcinogenic process for the activation of zinc metal in a medium polarity solvent, wherein said zinc metal is activated by the reaction thereof with a halogen and a lithium compound selected from lithium halide and lithium pseudohalides, the use of said activated zinc metal for the preparation of an organozinc halide of formula R-ZnX, and a process for the preparation of compounds obtainable by the reaction of said organozinc halide of formula R-ZnX with compounds having functionality enabling them to react with said organozinc halide.
