The reaction of diylids 1 toward carbonates, carbamates, thiocarbamates, isocyanates, carbodiimides and sulfinates allow the quantitative preparation of functional Wittig reagents, which can be used in situ in the E-stereoselective synthesis of the corresponding α,β-unsaturated derivatives of carboxylic (or sulfinic) acids. The diylids 2 or yldiid 3 can be used as synthetic equivalents of RNH2- or NH2- anions and allow normal or functional alkylation of the nitrogen atom.
Chemistry of (triphenylphosphoranylidene)sulfamoyl chloride. I. Reaction with amines and alcohols
Arrington, Dale E.

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.
