Microwave- and Ultrasound- Accelerated Green Permanganate Oxidation of Thioethersc

Abstract

Materials and Methods General Ultrasound irradiations were performed by means of a Branson 1210E-MT ultrasonic bath, operating at 47 kHz. Microwave irradiations were performed by means of a CEM MDS 200 batch microwave oven. GC/MS analyses were performed on a Hewlett Packard 5890 GC 5971A MS apparatus equipped with a J&W DB-5MS capillary column (30 m, 0.25 mm i.d., 0.25 μm film thickness) and a Hewlett Packard 7673A autosampler. NMR spectra were recorded on a Varian Mercury 300 NMR spectrometer. A suitable quantity of finely ground xPP/yCSP was added to a test tube (h=20.0 cm, d=3.0 cm) containing the thioether (following the
