Compounds containing sulfur–sulfur bonds (often called disulfides or more specifically disulfanes) are arguably one of the most valuable functional groups in organic synthetic chemistry. They exist extensively in nature, in which they exhibit important biological activities. Furthermore, a diverse range of natural and synthetic disulfides have been discovered that have many applications as pharmaceutical and agriculture chemicals as well as synthetic intermediates. Since thiols are commercially accessible or easily synthesizable materials and their choice as starting materials is widely reported for the synthesis of organic sulfur compounds, unsurprisingly the oxidative coupling of thiols is the best and simplest route for the preparation of disulfides. In recent times, nanocatalysts have shown excellent catalytic activity and reusability in the oxidation of thiols to disulfides. Herein, we summarize the recently reported breakthroughs in the use of nanocatalysts for the oxidative coupling of thiols to their corresponding disulfides, with the goal of stimulating further progress in this field.

Abstract This study investigated the pollution status of volatile organic sulfur compounds (VOSCs) and the factors influencing their spatial distribution in the Xi River in Shenyang, China. A method for simultaneous determination of 14 VOSCs that cause odor in water samples was developed by using purge and trap coupled with gas chromatography and a flame photometric detector. The results indicated that each target compound could be identified from 15 sampling sites, and the total concentration of 14 VOSCs ranged from 2.575 to 52.981 μg L−1. Dimethyl sulfide (DMS) was the most important contaminant with an average concentration of 4.029 μg L−1, a detection rate of 93.33% and a variation coefficient of 0.72. The VOSCs were primarily distributed in suburban and rural sections, and the suburban section was the worst in regard to pollution by VOSCs. Dimethyl trisulfide was primarily distributed in urban and suburban sections of the Xi River due to industrial emissions. Ethanethiol, DMS, and ethyl methyl sulfide, which are typical by-products of microbial anaerobic decomposition from domestic wastewater, were found in abundance in the suburban section. Diethyl sulfide, diethyl disulfide, methyl propyl disulfide, and 1-propyl disulfide representing agricultural nonpoint source pollution were mostly distributed in the rural section.
