Nacnac BnMgOtBu: 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 tert-butanol to form nacnacBnMgOtBu. The latter complex crystallizes as an alkoxide bridge dimer and is active in the ring-opening polymerisation of rac-lactide. Polymerisations at room temperature afforded atactic polylactide, while polymerisations at −17 and −26 °C afforded polylactide with a small isotactic bias (Pm = 0.52, and 0.55, respectively).
