ABSTRACT:
Novel compositions of matter herein are claimed and may be represented by the general formula CuA.L, where CuA is a Cu(I) salt of medium to strong Bronsted acids and L is a ligand chosen from a variety of structural classes including phosphines, phosphites, phosphine sulfides, phosphine oxides, thiophosphates, thioureas or arsines. These compositions are liquid at ambient conditions and are useful for complexing a variety of complexible organic compounds such as olefins, diolefins, allenes, acetylenes, aromatics, carbon monoxide and the like. In a preferred embodiment, the use of trialkyl phosphines is found to improve the stability of CuAlCl.sub.4.aromatic systems when said systems are used in olefin complexing processes.
