Abstract: Nitrogen-based variations of the bis(imino)pyridine incorporated late transition metal catalysts for olefin polymerization have recently attracted attention owing to their flexible complexation to transition metals. Because steric and electronic demands can be readily introduced to the iminopyrrole unit, a wide variety of ligands and corresponding complexes have been designed and synthesized. In this contribution, we briefly review reactivity and structural features of iminopyrrolyl ligands with early transition metals Ti and Zr, late transition metals Fe, Co, Ni, and Pd, rare earth metals Y, Ir, Lu, and Nd as well as other metals such as Cu, U, and Cr and their catalytic activity for olefin polymerization.

Key words: iminopyrrolyl ligand, transition metal complex, olefin polymerization, electronic effect
