Synthesis of cetyltrimethylammonium tribromide (CTMATB) and its application in the selective oxidation of sulfides to sulfoxides
摘要:
The bright yellow crystalline cetyltrimethylammonium tribromide (CTMATB) reagent has been synthesized from the reaction of CTMAB and KBr with H2MoO4.H2O, H2O2 and H2SO4 in the molar ratio 1:2:0.01:4:0.93. CTMATB selectively oxidizes a variety of dialkyl and alkyl aryl sulfides to the corresponding sulfoxides in high yields under mild conditions. (C) 2003 Elsevier Science Ltd. All rights reserved.

It has been observed that alkyl aryl and dialkyl sulfoxides can be conveniently and rapidly converted to the corresponding sulfides with an Al-NiCl2·6H2O system in high yields. Ketones are not affected under these reaction conditions.
