Abstract

Abstract : Investigation of a triamidoamine-supported zirconium hydride intermediate, important to a range of catalytic reactions, revealed the potential Lewis acidity of [κ 5 - N, N, N, N, C -(Me3 SiNCH2 CH2 )2 NCH2 CH2 NSiMe2 CH2 ]Zr (1 ). Abstract : Investigation of a triamidoamine-supported zirconium hydride intermediate, important to a range of catalytic reactions, revealed the potential Lewis acidity of [κ 5 - N, N, N, N, C -(Me3 SiNCH2 CH2 )2 NCH2 CH2 NSiMe2 CH2 ]Zr (1 ). A preliminary study of1 as a precursor for the polymerization of rac -lactide showed modest activity but indicated that five-coordinate zirconium complexes with tetra-N donor ligands may be an avenue for further development in group 4 metal lactide polymerization catalysis.
