Sulfamic acid halides and processes for the preparation of sulfamic acid halides

摘要

Sulfamic acid halides and processes for the preparation of sulfamic acid halides by reaction of monosubstituted sulfamic acid halides with halogen compounds in the presence of specific amounts of a basic compound and in the presence of an organic solvent, if desired with subsequent treatment with water at a pH of at most 7. The compounds obtainable by the process of the invention, some of which are new, are valuable starting materials for the preparation of crop protection agents, dyes and drugs.
