Transformation on Resin Sulfonic Acids

2-Diols have been reported to undergo the pinacol rearrangement in the presence of resin sulfonic acids to produce the corresponding carbonyl compounds in 80-90% yield. 

Nafion-H, a perfluorinated resin sulfonic acid, is also highly selective in the transformation of ditertiary 1,2-diols (benzene solution under reflux, 30 min)
