Utilizing a rigid terphenyl linker appended with various donors, a series of bimetallic polymerization catalysts has been prepared. Access to meta and para substitution allows for modification of the metal-metal distance and the steric profiles. Bimetallic complexes supported by phenoxy-imine and bisphenoxy amine ligands have been prepared and their chemistry explored with early and late transition metals. These bimetallic catalysts have shown, depending on the nature of the metal, tolerance of amines, polymerization of amino olefins, and tacticity control. The mechanism of their polymerization of a variety of monomers will be discussed.
