In this article, we report the oxidation of thiols by a hexamethylenetetramine-bromine complex. Our results are shown in Table I. This solid, an easily handled and storable reagent, allows for the conversion of thiols to disulfides. These reactions share the virtues of ease of operation; simplicity of product isolation; formation of products in high yields; and absence of side reactions, including over-oxidation and halogenation of the products. The ...
