Selective and Convenient Oxidation of Thiols to Disulfides Using n-Butyltriphenylphosphonium Dichromate (Bun PPh3)2Cr 2O7 in Solution, under Solvent-Free
Conditions and Microwave Irradiation. — The methods A)—C) produce comparable high yields of the disulfide products. However, the reaction time is considerably
reduced under microwave irradiation. A selective oxidation of thiol substrates in the
presence of sulfides [cf. (III)] is observed. — (MOHAMMADPOOR-BALTORK*, I.;
