Synthesis and rac-lactide ring-opening polymerisation studies of new alkaline earth tetrahydroborate complexes†‡
Abstract
Reaction of K[HC(C(Me)NAr′)2] (Ar′ = 2,6-C6H3iPr2) with Mg(BH4)2 afforded the pseudo four-coordinate tetrahydroborate complex Mg{HC(C(Me)NAr′)2}(BH4)(THF) (1). The corresponding reaction of Ca(BH4)2(THF)2 or Sr(BH4)2(THF)2 gave the pseudo five-coordinate analogues M{HC(C(Me)NAr′)2}(BH4)(THF)2 (M = Ca (2) or Sr (3)). All three compounds 1–3 have been structurally characterised. According to
