Abstract
A combination of a catalytic amount hydrobromic acid (10 mol%) and an excess of hydrogen peroxide is found to be an effective reagent for expeditious regeneration of carbonyl compounds from their 1, 3-dithiane as well as 1, 3-dithiolane derivatives. Absence of nuclear bromination of aromatic substrates and overoxidation of regenerated oxidation-prone aromatic aldehydes, compatibility with a number of functional groups, such as amino, ...
