Although the majority of aromatic sulfonyl chlorides are ..

SUBSTANCE: invention relates to perfluorinated sulfonyl halides of the formula: wherein L means component of a binding group; X means fragment chosen from the group consisting of fluorine (F), chlorine (Cl) atoms and -OH that represent modifying agents of polymeric backings. Activating agent bound with a backing is bound with a solid or semisolid backing by covalent bond. Also, invention describes a method for using activated backings in solid-phase organic synthesis.

Synthesis of Sulfonyl Chlorides and Sulfamides.

Radical chlorination of benzylic positions using sulfuryl chloride proceeds with good selectivity over less activated sites of reaction (eq 1). This reaction can be facilitated by transition metal complexes or zeolites.Certain substituted alkanes can also be selectively chlorinated by this method. A good example is Lampman and Aumiller's synthesis of 3-chlorocyclobutanecarboxylic acid (eq 2).Ionic chlorination of alkanes can be accomplished by heating a mixture of alkane and excess sulfuryl chloride in sulfolane (eq 3). In these chlorinations the reaction mixture is shielded from light to prevent the initiation of radical processes.

SUBSTANCE: invention relates to a method for synthesis of sulfonyl chlorides

SUBSTANCE: invention relates to a method for synthesis of alkylsulfochlorides of general formula CnH2n+1-mXmSO2Cl, where X denotes F or CI, n is an integer greater than 4, m is not greater than 2n+1, through oxidation of sulphur-containing organic compounds in an aqueous medium. The method is characterised by that sulphur-containing organic compounds are oxidised by adding a sodium hypochlorite solution to the reaction mass which contains an aqueous solution of hydrochloric acid and a sulphur-containing compound. Alkylsulfochlorides of the given formula can be used as catalysts in various chemical processes, as intermediate products in synthesis of biologically active substances, particularly herbicides, and for synthesis of surfactants.

The invention relates to a method of producing sulphonylchloride oxidation of thiols and disulfides. Sulphonylchloride used in the manufacture of detergents, ion exchange resins, elastomers, medicines, dyes, herbicides; as intermediates in the synthesis of esters of sulfonic acids; as well as soft alkylating agents in organic synthesis.

In organosulfur compound: Other sulfinyl and sulfonyl compounds

Sulfolane is quantitatively converted to -chlorosulfolane (eq 24).Alkyllithiums react with sulfuryl chloride in pentane at -65 to -20 °C to give sulfonyl chlorides in moderate yields. Aromatic sulfonyl chlorides can be prepared from aryllithiums by reaction with sulfur dioxide to form the sulfinate salts followed by oxidation with sulfuryl chloride (eq 25).Sulfuryl chloride oxidizes thiols to sulfonyl chlorides in the presence of potassium nitrate or in at 0 °C (eq 26). This transformation probably occurs via initial formation of the sulfenyl chloride followed by conversion to a sulfenyl nitrate and further oxidation.

Abstract Aromatic thiols were ..

The reaction of thioesters with sulfuryl chloride in carbon tetrachloride has been used in the synthesis of optically active sulfenyl chlorides (eq 22).Sulfoxides are rapidly -monochlorinated by sulfuryl chloride at -78 to 0 °C in dichloromethane containing CaO. Longer reaction times lead to ,-dichlorination.
