Abstract:

The reaction of sulfamic acid with PCl5, either in the absence or in the presence of a small quantity of CCl4 as a solvent, is an advantageous method for the synthesis of trichlorophosphazosulfonyl chloride. The latter material is an essential intermediate for the preparation of the trimer of sulfanuric chloride. Reactions of bis-trichlorophosphazosulfone and of the chlorides of N,N-dialkylsulfamido-N-phosphoric acid with Grignard reagents have lead to compounds in which the Cl atoms are all replaced by aryl groups. Thus far, only phenylmagnesium bromide has been caused to react with the corresponding chlorides. The synthesis of the unknown tribromophosphazosulfonyl bromide, by reaction of sulfamic acid with PBr3 and Br in CCl4 or stetrachloroethane as solvents, has been also attempted. Author
