In 2018,Devi, Namita; Hazarika, Sukanya; Gogoi, Prasanta; Barman, Pranjit published 《A novel dual-nano assisted synthesis of symmetrical disulfides from aryl/alkyl halides》.Synthetic Communications published the findings.Safety of 5-Bromo-2-chloropyridine The information in the text is summarized as follows:
A novel approach towards dual-nano assisted synthesis of disulfides from coupling of alkyl/aryl halides and sulfur nanoparticles has been reported. The indium oxide nanoparticles as catalyst expedite the conversion and sulfur nanoparticles notably enhances the miscibility, providing a faster, high yielding and cost-effective process in an ethanol-water system. The method has synthetic advantages in terms of mild reaction framework, catalyst regeneration, and absence of any sulfide or polysulfide linkage as byproduct leading to a column free synthesis. A variety of alkyl, aryl and heteroaryl sym. disulfides are obtained in good to excellent yields up to 98%.5-Bromo-2-chloropyridine(cas: 53939-30-3Safety of 5-Bromo-2-chloropyridine) was used in this study.
5-Bromo-2-chloropyridine(cas: 53939-30-3) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Safety of 5-Bromo-2-chloropyridine
