Remarkably Fast Deprotection of Semicarbazones and Tosylhydrazones Under Mild, Neutral and Solvent-Free Conditions

Remarkably Fast Deprotection of Semicarbazones and Tosylhydrazones Under Mild, Neutral and Solvent-Free Conditions

Rapid and selective regeneration of carbonyl compounds from their semicarbazones and tosylhydrazones was carried out using hexamethylenetetramine‐bromine (HMTAB) and N‐bromosuccinimide (NBS). Good to excellent yields, mild, neutral and solvent‐free conditions are important features of this method....
