We found that isopropyl and tert-butyl propargyl carbonates (1b and 1c) afforded high-molecular-weight polyethers compared with methyl propargyl carbonate (1a) in the polycondensation with ...

Timothy F. Jamison and colleagues' research, showing that trimethylsilyl groups can be used in a one-step epoxide-opening cascade reaction to prepare ladder polyethers, is significant and exciting ...
