Synthesis of novel polyethers with abundant reactive sites and diverse skeletons based on the ring-opening reaction of D–A cyclopropanes

Abstract

Based on the ring-opening reaction of D–A cyclopropanes, a facile synthesis of novel polyethers is developed with molecular weights up to 17.7 kg mol⁻¹. The resulting polymers possess diverse skeletons and abundant reactive gem-diester groups, which could be conveniently transformed into polyethers with a novel topology or bearing carboxylic acid groups.
