摘要：

The reactions of 2,2'-ethylidene-bis(4,6-di-tert-butylphenol) (EDBPH2) with sodium/potassium and (Bu-n)(2) - Mg in tetrahydrofuran (THF), give [(EDBP)(2) Mg][(Na)(2)(THF)(5)].THF (1) and [(EDBP)(2) Mg][(K)(2)(THF)(5)].THF (2) in high yield. Experimental results show that sodium/potassium complexes 1 and 2 are efficient catalysts for the ring-opening polymerization of lactides. Furthermore, complexes 1 and 2 have slight isotactic selectivity for the ring-opening polymerization of rac-lactide. (C) 2010 Elsevier B.V. All rights reserved.
