N,N'-Dibenzyl diketiminate copper isopropanolate, (nacnac(Bn)CuOiPr) 2, polymerizes rac- and S,S-lactide in the presence or absence of isopropanol as a chain-transfer reagent with very high activity (k(2) = 32 M-1 s(-1)), narrow polydispersities and without evidence of side reactions such as transesterification, epimerization or catalyst decomposition.
