Hexamethylenetetramine–Bromine: A Novel Reagent for Selective Regeneration of Carbonyl Compounds from Oximes and Tosylhydrazones†‡
Abstract
Hexamethylenetetramine–bromine (HMTAB) has been found to be an efficient and selective reagent for the mild oxidative cleavage of the CN of oximes and tosylhydrazones to yield their corresponding carbonyl compounds in good to excellent yields under mild conditions.
