α-Iminoenamido Ligands: A Novel Structure for Transition-Metal Activation

Abstract

This communication shows that it is possible to activate nickel complexes containing the α-iminoenamide ligand using B(C6F5)3 or Al(C6F5)3 to generate catalysts that polymerize ethylene. The polymerization of ethylene using these novel compounds is discussed. The novel activation method is confirmed by the X-ray crystallography studies of the methallyl analogs.
