Structural characteristics of organocuprates were studied by performing molecular orbital calculations on (CH3)4Li4, (CH3)4Cu4, (CH3)4Cu2Li2, (CH3)2(CH3O)2Cu2Li2, and (CH3)2(HC≡C)2Cu2Li2. It is found that organocuprates adopt planar structures, and alkyl groups or heteroligands of organocuprates are primarily bonded to copper instead of being equally coordinated to copper and lithium. An implication of these structural aspects of organocuprates on the selective addition to α,β-unsaturated carbonyls is briefly discussed.
