Abstract: Zn(N(SiMe3)2)2 was reacted with pyridinemethanol and R,R-N,N'-di(methylbenzyl)-2,5-diiminopyrrole (L1H) to afford the dimeric complex (L1)2Zn2(μ-OR)2. The complex showed moderate activity in rac-lactide polymerization to heterotactic polymer (Pr = 0.75). 2,4-Di-tert-butyl-6-aminomethyl-phenol ligands with amino = N,N,N',N'-tetramethyldiethylenetriamine (L2H)… read more here.
