Summary 1. A scheme explaining the reactions of amidation of carboxylic acids by amides of sulfuric acid is presented, and is experimentally established. 2. It is shown that phenylsulfamic acid in pyridine solution reacts with carboxylic acids to give their anilides. 3. The product of reaction of amines with acylsulfamic acids is shown to be an acylamine. 4. The products of reaction of p-aminobenzole acid with sulfamides are shown to be polypeptides of p-aminobenzoic acid. 5. A new method has been found for preparation of trihalogenophosphazosulfonaryls, from alkali metal salts of chloramides of arylsulfonic acids and appropriate phosphorus trihalides. 6. The hydrolysis and acidolysis of tricholorophosphazosulfonaryls have been studied. All the theoretically possible intermediate and final products of hydrolysis and acidolysis of trichlorophosphazosulfonaryls were obtained, viz, the mono- and di-chlorides of arylsulfonamidophosphoric acids, free arylsulfonamidophosphoric acids, and acylsulfamides. 7. The aminolysis and arylaminolysis of trichlorophosphazosulfonaryls have been studied. The products are: triamides of arylsulfonimidophosphoric acids, salts of diamides of arylsulfonimidophosphoric acids, mon-amides of arylsulfonamidophosphoric acids, chlorides of dianilidoarylsulfonimidophosphoric acids, diamilides of arylsulfonamidophosphoric acids, and trianilides of arylsulfonimidophosphoric acids. 8. The reaction between trichlorophosphazosulfonaryls and alcohols or phenols has been studied. The products are triesters of arylsulfonimidophosphoric acids and diesters of arylsulfonamidophosphoric acids.
