Abstract
A 1:1 adduct of dimethylzinc and (-)-sparteine has been prepared and c haracterized crystallographically; the complex is remarkably resistant to reaction with the atmosphere. The adduct is mononuclear with pseud o-tetrahedral coordination at the zinc atom. It reacts with benzoyl ch loride to give acetophenone and with benzaldehyde to give (R)-1-phenyl ethanol with a 15% enantiomeric excess.
