In our experiments where Dowex-1 anion exchange resin, in its hydroxide form, was used in place of alkali or quaternary ammonium hydroxides, the yields of reactions 1 and 2 were 80- 95% and 50-60%, respectively. The diols (OH-R-OH) used were ethylene glycol, diethylene glycol, 1, 4-butanediol, and 1, s-pentanediol. Aside from the high yields obtained for reactions 1 and 2, it was also observed that considerably cleaner product mixtures were ...
