1,127,655. Phosphoric acid diester-(N-sulphonyl)-amides containing acylamino groups. FARBENFABRIKEN BAYER A.G. 18 May, 1966 [24 May, 1965], No. 22133/66. Heading C2C. [Also in Division C3] Novel phosphorus-containing compounds of the general formula wherein R1, R2, R3 and R4, which may be the same or different, are hydrogen atoms or alkyl radicals; R5 is an alkyl or aryl radical and A is an alkylene or arylene radical, are prepared by reacting phosphoric acid diester-N-aminosulphonamides of the general formula with reactive derivatives of unsaturated carboxylic acids, e.g. of the formula wherein X is a halogen atom or a radical of the type:- The reaction is preferably carried out by treating equivalent quantities of II and III in acetic acid solution and then acidifying with HCl. A temperature of - 15‹- + 50‹ C. is used. Compounds of the Formula I may also be prepared by reacting unsaturated polymerizable sulphonamides with diester chlorides of phosphoric acids or by reacting unsaturated polymerizable sulphonamides with PCl 5 and saponifying to give the required product. The products are useful in the production of polymers and copolymers. The aminosulphonamides II may be prepared by reacting nitrobenzene sulphonamides with PCl 5 , hydrolysing and then treating with phenols or alcohols to give the phosphoric acid diester - (N - nitrobenzenesulphonamides), which can be reduced directly to the corresponding amine.
