摘要

Coordination-insertion copolymerization of non-polar olefins and polar monomers by late transition metal catalysts is a powerful method to synthesize functionalized polyolefins [1].Seminal successes in this copolymerization have been achieved by using group-10 metal catalysts bearing a bidentate ligand such as phosphine-sulfonate and bisphosphine monoxide (BPMO) (Figure 1) [1].These ligands typically consist of a strong σ-donor and a weak σ-donor and have an arylene linker between the two coordination sites (Figure 1,middle).Although a variety of coordination sites have thus far been investigated,less attention has been paid to the influence of the backbone structure.Recent papers shed light on this issue.
