Synthesis of diacetals from aldehydes and ketones with pentaerythritol catalysed by the ZrO2/S2O82- solid superacid

Abstract

A manipulatively simple and rapid procedure for the synthesis of diacetals from 2,2-bis(hydroxymethyl)-1, 3-propanediol with aldehydes and ketones in refluxing benzene or toluene using the ZRO2/S2O 82- solid superacid as catalyst in 80-98% yields has been described.
