Secondary benzylic ethers undergo stereospecificsubstitutionreactions with Grignard reagents in the presence of nickel catalysts. Reactions proceed with inversion of configuration and high stereochemical fidelity. This reaction allows for facile enantioselective synthesis of biologically active diarylethanes from readily available optically enriched carbinols.

Alkyl Grignard reagents that contain β‐hydrogen atoms were used in a stereospecific nickel‐catalyzed cross‐coupling reaction to form C(sp3)C(sp3) bonds. Aryl Grignard reagents were also utilized to synthesize 1,1‐diarylalkanes. Several compounds synthesized by this method exhibited selective inhibition of proliferation of MCF‐7 breast cancer cells.
