Abstract:
The published data on the synthesis of organomagnesium compounds assisted by metal complex catalysts are generalised and described systematically for the first time. Hydro-, carbo- and cyclomagnesiation reactions of unsaturated compounds with R1MgR2 (R1 = Alk, Ar; R2 = H, Hal; R1 = R2 = Alk) catalysed by Ti, Zr and other transition metal salts and complexes are considered. Selected examples of applications of organomagnesium reagents to organic synthesis are given.
