Chisholm, Malcolm H., Patmore, Nathan J. and Zhou, Zhiping (2005) 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). Chemical Communications (1). pp. 127-129. ISSN 1359-7345

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.
