p-Toluenesulfonic Acid Adsorbed on Silica Gel: An Efficient Dehydrating Agent of Alcohols

Secondary and tertiary alcohols are efficiently dehydrated by reaction with p-toluenesulfonic acid supported on silica gel.In particular, the procedure allows the direct conversion of 3-hydroxy-steroids into Δ2-olefins or Δ3,5-dienes, without passing through the mesylate or tosylate esters.
