Compounds of the type Ph3PNSO2OR and Ph3PNSO2NHR (R = Me, Et, n-Pr, n-Bu, and o-, m-, p-BrC6H4) have been prepared in good yield by the reaction of (triphenylphosphoranylidene)sulfamoyl chloride, Ph3PNSO2Cl, with alcohols in pyridine or with amines in chloroform; derivatives of secondary amines may also be prepared by the latter method. Heating the methyl ester in pyridine to moderately high temperatures produces a compound containing the Ph3PNSO2O- ion which yields the free acid upon acidification. The infrared spectra of the title compound and the alkyl esters in the 1100-1300-cm-1 region are presented and discussed.
