Synthesis of cyclic ethers by cyclodehydration of 1,n-diols using heteropoly acids as catalysts [PDF]
Royal Society Open Science, 2018 Heteropoly acids were used as catalysts for cyclodehydration of various 1,n-diols. Cyclodehydration of butane-1,4-diol, pentane-1,5-diol and hexane-1,6-diol catalysed by H3PW12O40 gave tetrahydrofuran, tetrahydropyran and oxepane, respectively ...

Acid Site Design for Low Hydration Proton Exchange Membranes
Advanced Functional Materials, EarlyView.α‐CF2 substitution adjacent to sulfonic acid increases acid strength and enables efficient proton transport under low hydration conditions. This molecular design reduces the dependence of hydrocarbon proton exchange membranes on excessive water uptake, addressing a key limitation of conventional hydrocarbon PEMs while maintaining favorable conductivity
