Abstract

The reaction of Sm{N(SiMe3)2}3 with the bis(phenol)amines H2O2NR (H2O 2NR = RCH2CH2N(2-HO-3,5-C 6H2tBu2)2; R = OMe, NMe2 or Me) gave exclusively zwitterions Sm(O2N R)(HO2NR). For R = OMe or NMe2 these were efficient catalysts for the ring-opening polymerisation of e-caprolactone and d,l-lactide with a tendency to form cyclic esters; in contrast, no polymerisation was observed for R = Me. © The Royal Society of Chemistry.
