Rules relating the conformation of the catalytic complex and configuration of the reaction products are proposed for the cross-coupling reactions of alkyl (aryl) or sec-alkyl Grignard reagents and organozinc compounds with derivatives of olefins in the presence of nickel complexes containing chiral diphosphine or phosphine amine ligands.The rules were checked in the cross-coupling reactions of arylmagnesium bromides with crotyl alcohol and 1-(4-isobutylphenyl)ethylmagnesium bromide with vinyl bromide in the presence of NiCl2/S-Phephos (optical yields 29-83percent).

Chiral β-dimethylaminoalkylphosphines were prepared starting with amino acids, (S)-alanine, (S)-phenylalanine, (R)-phenylglycine, (S)-valine, and (R)-tert-leucine. The chiral phosphines were found to be highly efficient ligands for a nickel catalyzed asymmetric Grignard cross-coupling reaction (38~94% optical yield).
