Allylic gem-dichlorides undergo regio- and enanantioselective (er up to 99:1) copper-catalyzedallylicalkylation with Grignard reagents affording chiral Z-vinyl chlorides. This highly versatile class of synthons can be subjected to Suzuki cross coupling affording optically active Z-alkenes and 1,3-cis,trans dienes.
