3. Efficient and Convenient Oxidation of Thiols to Symmetrical Disulfide with Silica–PCl5/NaNO2in Water

Author

Uma Pathak, Lokesh Kumar Pandey, and Sweta Mathur

Subjects
Aqueous medium, Chemistry, Organic Chemistry, Disulfide bond, Organic chemistry
Abstract

A very simple, environmentally benign, cost-effective, and efficient synthesis of disulfides from thiols using silica–PCl5/NaNO2 in aqueous medium has been described. The reaction was found to occur rapidly under mild conditions, and disulfides were obtained easily through a simple workup.

4. Silica–PSCl3: A Mild and Efficient Reagent for Deoxygenation of Sulfoxides

Author

Uma Pathak, A. Narasimha Rao, and Lokesh Kumar Pandey

Subjects
law, Chemistry, Reagent, Organic Chemistry, Organic chemistry, Deoxygenation, Filtration, law.invention
Abstract

A new solid supported reagent, silica–PSCl3, has been developed for deoxygenation of sulfoxides. With this reagent, conversion of sulfoxides to sulfides occurred cleanly and efficiently at room temperature. Facile isolation of the product was achieved by simple filtration of the by‐products without any extensive workup.
