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.
