Bimetallic Complexes

Homo-dinuclear Co or Zn complexes derived from a [2+2] Schiff-base macrocycle revealed near inactivity for the ring opening polymerization of δ-valerolactone and ε-caprolactone, whereas hetero-bimetallic complexes were efficient catalysts.

Schiff Base Metal Complexes

This review describes the recent advances (from 2008 onwards) in the use of Schiff-base metal complexes as catalysts for the ring opening polymerization (ROP) of cyclic esters. The synthesis and structure of the metal complexes, as well as all aspects concerning the polymerization process and the characteristics of the polymers formed, will be discussed.
