Determination of the Degree of Aggregation of Organocopper Compounds by Cryoscopy in Tetrahydrofuran

Abstract

Organocuprates are mostly monomeric in solution! This is the result of the investigation of the aggregation behavior of reagents with the stoichiometry [R2Cu(X)Li2], carried out for the first time by cryoscopy in tetrahydrofuran. Thus, Gilman cuprates (X = I) and cyanocuprates (X = CN) may belong to the same structural type 1.
