Abstract

Abstract Two novel Zr IV-and Hf IV-based bisamido complexes bearing the 6-[2- (diethylboryl) phenyl] pyrid-2-yl motif, that is,[ZrCl 2 {Me 2 Si (DbppN) 2}(thf)](9) and [HfCl 2 {Me 2 Si (DbppN) 2}(thf) 2](10)(DbppN= 6-[2-(diethylboryl) phenyl] pyridine-2-amido) have been prepared. Their reactivities have been compared with that of a model precatalyst that does not bear the aminoborane motif. Upon activation with methylalumoxane, precatalysts ...
