资源简介：
A new chromium(III) complex (2) with a readily
available
aminotriphenolate ligand (LtBu,tBu) was developed as an efficient catalyst for alternating ring-opening
copolymerization of cyclic epoxides and anhydrides to afford polyesters.
The single-crystal structure of 2 exhibits an octahedral
geometry despite the high steric profile of LtBu,tBu. After the reaction conditions were optimized,
complex 2 in the presence of a cocatalyst produced perfectly
alternating polyesters with high molecular weights (up to Mn = 44.2 kg/mol) and low dispersity at high
conversion. In addition, various polyesters prepared using combinations
of comonomers exhibited relatively high glass transition temperatures.
