Abstract

Homo-dinuclear complexes Co and Zn complexes derived from the macrocycle LH2, {[2-(OH)-5-(R)-C6H2-1,3-(CH)2][CH2CH2(2-C6H4N)2]}2 (R = Me, tBu), revealed near inactivity for the ring opening polymerization (ROP) of the cyclic esters δ-valerolactone (δ-VL) and ε-caprolactone (ε-CL). By contrast, the hetero-bimetallic complexes [LCo(NCMe)(µ-Br)ZnBr]·nMeCN (n=3 or 3.25) were found to be efficient catalysts for the ROP of ε-CL and δ-VL.
