Abstract
Cs2.5H0.5PW12O40 consisting of ultrafine crystallites efficiently cata lyzes pinacol rearrangement of 1,1,2-triphenyl-1,2-ethanediol at room temperature in solid-solid reaction system, giving the corresponding a ldehyde selectively, while p-toluenesulfonic acid, H-ZSM-5, HY, SiO2-A l2O3, SO42-/ZrO2 and Nb2O5 . nH(2)O were inactive. The activity of Cs2 .5H0.5PW12O40 in the solid-solid reaction was higher than that in soli d-liquid (CHCl3) system.
