Hydrotalcite is an efficient catalyst for air oxidation of a variety of aromatic, aliphatic and alicyclic thiols in hexane, affording the corresponding disulfides in excellent to quantitative yields under mild and neutral conditions.
An inexpensive combination of common laboratory reagents, dimethyl sulfoxide (DMSO) and chromatographic neutral alumina, gives an efficient, selective, and high-yielding oxidation of aromatic, aliphatic and alicyclic thiols to the corresponding disulfides in excellent yields under relatively mild conditions.

Aromatic, aliphatic, and alicyclic thiols readily underwent oxidative coupling with chemical manganese dioxide in hexane to afford the corresponding disulfides in essentially quantitative yields under relatively mild conditions.
A variety of aromatic, aliphatic, and alicyclic thiols were readily oxidised with a combination of sodium iodate and chromatographic neutral alumina in hexane to afford the corresponding disulfides in excellent yields under mild and neutral conditions.
nontoxic to the normal cells. Based on the LD50 values and selectivity index (SI), compound 3h (S-p-methoxybenzyl (p-methoxyphenyl)methanesulfinothioate) was considered as most promising anticancer agent amongst the above three compounds. Further bio-chemical studies confirmed that compound 3h promotes ROS generation, changes in mitochondrial permeability transition and induced caspase mediated DNA
