Definitions

  • This invention relates to a process for producing sulfamides, and to novel intermediates used in the process .
  • Sulfamides are conventionally prepared by the use of strongly electrophilic reagents such as sulfamoyl chloride, sulfonyl dichloride, phosphorus oxychloride or phosphorus pentachloride .
  • Belgian patent 667.311 discloses a method of making sulfamides employing an N-alkyl sulfamoyl chloride.
  • all such reagents involve aggressive synthetic methods, and indeed can be inconvenient or dangerous in their practical, industrial, application.
  • the invention provides a process for the production of aryl sulfamides that avoids the use of the above hazardous materials and conditions, and gives a high yield.
