Process for the manufacture of N-(beta- diorganodithiophosphorylethyl) aryl and alkyl sulfonamides

摘要

N-(beta-diorganodithiophosphorylethyl) aryl and alkyl sulfonamides are prepared by a process comprising reacting a compound having the formula R. sup.1 SO.sub.2 X with 2-aminoethyl hydrogen sulfate and an aqueous solution of M.sup.1 OH, and reacting the resulting product with a compound having the formula ##STR1## In the above description, R. sup.1 is selected from the group consisting of C.sub.1 -C.sub.10 alkyl, halo- substituted C.sub.1 -C.sub. 10 alkyl, phenyl, halo-substituted phenyl, nitro-substituted phenyl, and naphthyl; R.sup.2 and R.sup.3 are independently selected from the group consisting of C.sub.1 -C.sub.10 alkyl and C.sub.1 -C.sub.10 alkoxy; X is selected from the group consisting of chloride, bromide, and iodide; and M.sup.1 and M.sup. 2 are independently selected from the group consisting of lithium, sodium, potassium, ammonium, and tri-substituted ammonium wherein the substituents are independently C.sub.1 -C.sub.10 alkyl.
