Abstract
[7205-94-9] C7H7ClOS (MW 174.65) InChI = 1S/C7H7ClOS/c8-6-10(9)7-4-2-1-3-5-7/h1-5H,6H2 InChIKey = WCUSVVDFUIMPKY-UHFFFAOYSA-N (synthesis of α,β-epoxy sulfoxides;2a–c one-carbon homologating agent3) Physical Data: bp 120–121 °C/4 mmHg. Solubility: sol CHCl3 and THF. Preparative Methods: chlorination of methyl phenyl sulfoxide with either Sulfuryl Chloride4 in methylene chloride or N-Chlorosuccinimide5 in chloroform gives a good yield of the product. A one-pot procedure starting with Thioanisole consists of chlorination with sulfuryl chloride in methylene chloride6 followed by oxidation with the same reagent in the presence of wet silica gel.7 Another alternative is to employ Silver(I) Nitrate and sulfuryl chloride in acetonitrile.8 Handling, Storage, and Precautions: use in a fume hood.
