Ap. Bandgar et Ss. Makone, Remarkably fast deprotection of semicarbazones and tosylhydrazones under mild, neutral and solvent-free conditions, J CHIN CHEM, 47(3), 2000, pp. 575-577
Rapid and selective regeneration of carbonyl compounds from their semicarba
zones and tosylhydrazones was carried out using hexamethylenetetramine-brom
ine (HMTAB) and N-bromosuccinimide (NBS). Good to excellent yields, mild, n
eutral and solvent-free conditions are important features of this method.
