Alkylation of copper(II) acetate with dialkylmagnesium reagents in the presence of tertiary phosphines gives the colorless copper(I) alkyl species. With sterically small phosphines, the complexes are ionic and possess left bracket Cu(PR//3)//4 right bracket cations and left bracket CuR//2 right bracket anions; larger phosphines give electrically neutral CuR(PR//3)//3 coordination complexes. Solution NMR data indicate that reversible phosphine dissociation is a facile process for all of the complexes and that extensive ion pairing occurs in nonpolar solvents. The X-ray crystal structure of the dimethylcuprate complex has been determined.
