The path of the reaction of aryl-N-(p-toluenesulfonyl)-sulfinimidoyl fluorides and triphenylphosphine is highly dependent on the order of the reactants addition. Addition of triphenylphosphine to aryl-N-(p-toluenesulfonyl) -sulfinimidoyl fluorides results in the formation of triphenyl(arylthio) phosphonium salts of N,N′-bis(p-toluenesulfonyl)aryl-sulfinamidines and triphenyldifluorophosphorane. By changing the reagent addition order, we obtained triphenyldifluorophosphorane, P, P, P-triphenyl- N- (p-toluenesulfonyl)-phosphine imide, and diaryl disulfides. The outcome of the reaction aryl-N-(arenesulfonyl)-sulfinimidoyl chlorides and triphenylphosphine does not depend on the order of addition of the reactants. P,P,P-Triphenyl-N- (arenesulfonyl)-phosphine imides, triphenyldichlorophosphorane, and diaryl disulfides were formed as a result.

The ability of N-substituted sulfenamides to be iminated by the sodiochloroamides of sulfonic acids is due primarily to their acidity and to the type of solvent employed.N-Substituted sulfonamides with pKa > 11.0 are imidated by the sodiochloroamides of sulfonic acids in acetone.The imination of N-substituted sulfenamides with pKa 8-11 must be carried out in strongly basic solvents with high dielectric constants (an aqueous alkaline medium, pyridine, etc.); sulfenamides with pKa 8 are iminated by the sodiochloroamides of sulfonic acids in the form of the sulfenamide anion.

Disulfides react with chloramine T in alcohols to give a mixture of N-tosylamides and alkyl esters of N-tosylalkane- or N-tosylarene-sulfinimidic acids.
