Ethyl copper (CuC2H5) is an organocopper compound consisting of copper in its +1 oxidation state (cuprous) bound to an ethyl group. It can be generated by transmetallation by the reaction of copper(I) acetate with tetraethyl lead:[1]

CuOAc + Pb(C2H5)4 → CuC2H5 + Pb(C2H5)3OAc

Methyl copper was obtained from methyl lithium and copper(I) iodide at low temperature.[2]

A copper ethyl complex has been characterized by X-ray crystallography.[3]
