Sulfinyl and Sulfonyl Chlorides by Chlorination^1,2

Chromoselective Synthesis of Sulfonyl Chlorides and Sulfonamides with Potassium Poly(heptazine imide) Photocatalyst

“…The excess of chlorine leads to over‐chlorination of sulfenyl chloride with formation of unstable arylsulfur trichlorides, which quickly decompose to afford arylchlorides. [29] …”

A new synthesis of alkane and polyfluoroalkanesulfonyl chlorides

“…All alkanesulfonyl chlorides and polyfluoroalkanesulfonyl chlorides have been identified by comparison of their 1 H and 13 C NMR spectra with those authentic samples of analytical purity. Melting points were recorded at atmospheric pressure unless otherwise stated on a Stuart scientific SMP3 apparatus and remained without any correction.…”

“…Amongst these methods, the more important involve the aqueous chlorination of disulfides and thiols [8]. Different sulfur compounds have also been converted to alkanesulfonyl chlorides, e.g., thiols [8], sulfides [9], thiocyanates [10], isothiouronium salts [11], S,S-dialkyl dithiocarbonates [12], thiol esters [8], thiosulfonates [8], sulfinyl chlorides [13], and sulfinic acids [14]. However, the disadvantages of the most of these methods are the preparation of starting materials, or unsatisfactory reaction yields or the production of side products.…”

Biosynthesis of ethylene. Methanesulphinic acid as cofactor in the enzymic formation of ethylene from methional

“…Final purification was achieved by preparative gas-liquid chromatography on silica gel, details of which were also given by Mapson & Mead (1968 Sources of sulphinic acids. Methanesulphinic acid was prepared from methanesulphinyl chloride by the method described by Wudl, Lightner & Cram (1967), the sulphinyl chloride being itself prepared from dimethyl disulphide by the procedure of Douglass, Farah & Thomas (1961 Benzenesulphinic acid (sodium salt) was purchased from British Drug Houses Ltd. (Poole, Dorset). Cysteinesulphinic acid was purchased from Sigma (London) Chemical Co. (London, S.W.…”
