Copper Imidazolin-imine Coordination Compounds as Precursors for a Cu/Al Complex.

ABSTRACT: The reactions of [(CF₃SO₃Cu)₂(C₆H₆)] with the sterically hindered imidazolin-2-imine ligands DippImTMS (1,3-Bis(2,6-diisopropylphenyl)-2-(trimethylsilylimino)imidazoline) or DippImH (1,3-bis(2,6-diisopropylphenyl) imidazolin-2-imine) lead to the formation of the linear copper(I) complexes [Cu(DippImTMS)(OTf)] (1) and [Cu(DippImH)₂][OTf] (2), respectively. The triflate counteranion in 2 can be easily exchanged to the weakly coordinating [BAr^F] giving [Cu(DippImH)₂][BAr^F] (3) (BAr^F = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate). Substitution of the N-heterocyclic imine (NHI) ligand in 3 by AlCp* (Cp* = pentamethylcyclopentadienyl) gives the tetra
