Abstract

The photodecomposition of carbon tetrachloride was studied under sonication in the presence of N-(tert-butyl)benzothiazole-2-sulfenamide (TBBS), N-(cyclohexyl)benzothiazole-2-sulfenamide (CBS), and 2-sulfanylbenzothiazole (MBT) as electron donors. By following the concentrations of Cl− and C2Cl6 as a function of time, it was shown that ultrasound decreases their rate of formation when TBBS and CBS were used, but it has no effect in the presence of MBT. These observations were rationalized by a cavitation-induced destabilization of the contact ion pair (CIP) formed from exciplexes.
