Abstract
Producing polyesters with high molecular weight (Mn ) through ring-opening copolymerization (ROCOP) of epoxides with cyclic anhydrides remains a major challenge. Herein, we communicate a metal-free, highly active, and high thermoresistance system for the ROCOP of epoxides with cyclic anhydrides to prepare polyesters (13 examples). The organoboron catalysts can endure a reaction temperature as high as 180â°C for the ROCOP of cyclohexane oxide (CHO) with phthalic anhydride (PA) without the observation of any side reactions. The average Mn of the produced poly(CHO-alt-PA) climbed to 94.5â
kDa with low polydispersity (Ă=1.19). Furthermore, an unprecedented turnover number of 9900, equivalent to an efficiency of 7.4â
kg of polyester/g of catalyst, was achieved at a feed ratio of CHO/PA/catalyst=20000:10000:1 at 150â°C. Kinetic studies, crystal structure analysis, 11 Bâ
NMR spectra, and DFT calculations provided mechanistic justification for the effectiveness of the catalyst system.
