Making a swap : The titled studies provide substantial evidence for the kinetically labile Mg 2+ ion reacting through both a dissociative (see scheme; thf=tetrahydrofuran) and an associative interchange mechanism. The findings are particularly relevant to the reactions involving [LMg n Bu(thf)] and rac‐ lactide in ring‐opening polymerization reactions.
