25. To a solution of alkane/arenethiol (1 mmol) in dichloromethane, silica chloride (5 mol %) was added at 0°C and access to atmospheric oxygen. The reaction mixture was stirred for 10 min; the progress of reaction was monitored by TLC and also by gas chromatography. After the completion of reaction, mixture was filtered off and filtrate was concentrated to afford dialkyl/aryl disulfide in a quantitative yield. The physical properties and NMR spectra of compounds agreed with those reported in the literature.
