| abstract | 1,252,903. Halosulphonylalkyl nitriles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 April, 1969 [10 May, 1968], No. 22324/68. Heading C2C. Novel compounds I: wherein X signifies F, Cl or Br and R<SP>1</SP> and R<SP>2</SP> signify H or straight chain C 1-6 alkyl, are obtained by reacting a compound II (obtained by treating an appropriate bromo- or chloroalkane nitrile with sodium sulphite): with a mixture of phosphorus oxychloride and phosphorus pentachloride to afford compounds I wherein X is Cl or with phosphorus pentabromide to afford compounds I wherein X is Br; compounds I wherein X is F may be obtained from the corresponding chloro.compounds utilizing an alkali metal fluoride. 2,4-Dichloroaniline is reacted with 2-chlorosulphonyl-acetonitrile to afford 2,4-dichlorophenylsulphamoyl-acetonitrile; 2-(2,4-dibromophenylsulphamoyl)-valeronitrile is similarly obtained. Isobutylamine reacts with compounds I to afford the following products: and Phenylsulphamoyl-acetonitrile, obtained by the interaction of aniline and 2-chlorosulphonylacetonitrile, reacts with 2,4-dichloro-benzenediazonium chloride to yield 2,4-dichlorophenylhydrazono-acetonitrile. |
