摘要：NOVELTY - A new metallic complex (II) includes quinoline-substituted aminoindole ligand (I). USE - New metallic complex is used as catalyst in ring-opening polymerization of L-lactide, D-lactide, rac-lactide, meso-lactide, epsilon -caprolactone, gamma -butyrolactone and alpha -methyltrimethylene cyclic carbonate (all claimed). ADVANTAGE - The metallic complex having high catalytic activity is manufactured efficiently with high yield by simple method. DETAILED DESCRIPTION - A new metallic complex of formula (II) includes quinoline-substituted aminoindole ligand of formula (I). R1=H or halo; A1,A2=group of formula (a) or (b); R2,R3=H or linear or branched 1-10C alkyl; M=zinc, magnesium or calcium;and X=linear or branched 1-6C alkyl, linear or branched 1-6C alkoxy, bis(trimethylsilyl)amino or bis(dimethylsilyl)amino. INDEPENDENT CLAIMS are included for the following: (1) manufacture of metallic complex (II); and (2) usage of metallic complex (II) as catalyst in ring-opening polymerization of L-lactide, D-lactide, rac-lactide, meso-lactide, epsilon -caprolactone, gamma -butyrolactone and alpha -methyltrimethylene cyclic carbonate.
