Abstract
The catalyzed cross‐coupling reaction of secondary racemic Grignard reagents with unsaturated halides takes place stereospecifically in the presence of the nickel chiral complex 4 although some isomerisation is occurring this reaction can be useful to prepare optically active hydrocarbons.
