Fast, efficient and convenient method for the preparation of arylazo sulfides using aryl diazonium silica sulfates under mild and solvent-free conditions
摘要:
An efficient, fast, and straightforward procedure for the synthesis of arylazo sulfides and arylazo thiosulfonates is described in the present paper by using aryl diazonium silica sulfates and sodium thiolates. Using the present method, different kinds of aryl diazonium silica sulfates, containing electron-withdrawing groups as well as electron-donating groups, were rapidly converted to the corresponding arylazo sulfides in good yield and short reaction time. These reactions were carried out at room temperature under mild and solvent-free conditions. The use of non-toxic and inexpensive materials, simple and clean work-up, short reaction times and good yields are the advantages of this method. (C) 2011 Elsevier Ltd. All rights reserved.
