摘要：

Making a swap: The titled studies provide substantial evidence for the kinetically labile Mg2+ ion reacting through both a dissociative (see scheme; thf=tetrahydrofuran) and an associative interchange mechanism. The findings are particularly relevant to the reactions involving [LMgnBu(thf)] and rac-lactide in ring-opening polymerization reactions. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
