Organocopper complexes carboxylates

The formation of transient organocopper compounds has been inferred in many decarboxylations of copper(I) carboxylates or copper-carboxylic acid systems 20, 33, 47, 56, 211, 213, 215, 279). Only one copper compound has been isolated, so far. Tbe decarboxylation of copper(I) pentafluorobenzoate in quinoline proceeds smoothly at 60°C to give a pentafluorophenylcopper-quinoline complex 33, cf. 254).
