Monoorganomagnesium heteroleptic compounds

For the synthesis of heteroleptic monoorganomagnesium compounds, three major pathways are available (Scheme 1). 

The third pathway (Scheme 1) for the preparation of heteroleptic monoorganomagne-sium compounds, especially monoorganomagnesium halides, involves the reaction of an organic halide with metalhc magnesium, the classical Grignard reaction (equation 14). 

The structures of only a very few heteroleptic monoorganomagnesium compounds with a magnesium-heteroatom bond with heteroatoms other than halogen, oxygen or nitrogen have been determined.
