A Convenient Deprotection of 1,3-Dithiane Derivatives with Ferric Nitrate Under Heterogeneous Conditions

Abstract

1,3-Dithianes derived from aromatic, aliphatic, and alicyclic ketones or aldehydes can be conveniently converted to the parent carbonyl compounds with a combination of ferric nitrate and silica gel in hexane in excellent to quantitative yields.
