Abstract
A new ligands that include a benzene ring in the backbone can be combined with a metal or metal precursor compound or formed into a metal-ligand complex catalyze a number of different chemical transformations, including olefin polymerization reactions. The ligands, complexes formed with the ligands and compositions including the ligands are useful catalysts, depending on the reaction.
