Cationic PdII, NiII, and RuII complexes in the synthesis of alternating copolymers of NO with vinyl monomers

Abstract

The history and state-of-the-art of the synthesis of alternating copolymers of CO with vinyl monomers in the presence of PdII, NiII, and RuIIcomplexes are considered. The influence of P∩P, P∩N, and N∩N mono- and bidentate ligands and the nature of the reaction medium and the acid on the rate of CO copolymerization with ethylene and on the structure and some properties of optically active CO—propylene and CO—styrene copolymers is discussed. A possible mechanism of CO and ethylene copolymerization in the presence of PdIIcomplexes is proposed.
