Description
Summary:The reaction of bidentate N,N-dimethylaniline-arylamido ligands,o-C6H4NMe2（CH2NHAr）（Ar =Ph,1a;2,6-Me2C6H3,1b; 2,6-Et2C6H3,1c; 2,6-ipr2C6H3,1d） with ZnEt2 yields the complexes o-C6H4（NMe2）（CH2NAr）ZnEt （2a-2d）,respectively.All the complexes were characterized by 1H and 13C NMR spectroscopy and elemental analyses.It was found that all the zinc complexes were efficient catalysts for the ring-opening polymerization of L-lactide in the presence of benzyl alcohol with good molecular weight control and narrow polydispersity.
