An Aluminum Complex Supported by a Fluorous Diamino-Dialkoxide Ligand for the Highly Productive Ring-Opening Polymerization of ε-Caprolactone

The new discrete aluminum alkoxide complex (iPrO)Al{CH2NMeCH2C(CF3)2O}2 (1) initiates the controlled ring-opening polymerization of caprolactone in dichloromethane at 20 °C with high activity (TOF = 250 h-1) and productivity (TON up to 1000), leading to polymers with high molecular weight and narrow molecular weight distribution.新型离散型烷氧基铝配合物(iPrO)Al{CH2NMeCH2C(CF3)2O}2（化合物1）可于20 ℃下在二氯甲烷中引发己内酯的可控开环聚合，展现出高催化活性（转换频率TOF = 250 h⁻¹）与高催化产率（转换数TON最高可达1000），所得聚合物兼具高分子量与窄分子量分布特征。
