NacnacBnMgOtBu: a diketiminate-based catalyst for the polymerisation of rac-lactide with slight isotactic preference†
Abstract
The reaction of N,N′-dibenzyl-2-amino-4-imino-pent-2-ene, nacnacBnH, with 1 or 2 equiv. of MgnBu2 afforded the homoleptic complex nacnacBn2Mg. The reaction of nacnacBnH with Mg(N(SiMe3)2)2 yielded nacnacBnMgN(SiMe3)2, which reacted with
