Concerning the relative importance of enantiomorphic site vs. chain end control in the stereoselective polymerization of lactides: Reactions of (R,R-salen)- and (S,S-salen)-aluminium alkoxides LAlOCH2R complexes (R = CH3 and S-CHMeCl)

Abstract

The preparations and structures of LAlOCH2C(S)HMeCl, where L = (R,R) or (S,S)-N,N′-bis(3,5-di-tert-butyl-salicylidene)-1,2- cyclohexenediamino, are reported together with the respective LAlOEt compounds, and their reactivities toward L- and rac-lactides in various solvents reveal the surprising complexity of the stereopreference for the ring-opening event.
