Claims
- 1. A process for the manufacture of sulfonyl dicarboxamides of the formula ##STR5## wherein R and R' may be the same or different and are C.sub.1 to C.sub.8 alkylamino, di C.sub.1 to C.sub.8 alkylamino, phenylamino, diphenylamino, C.sub.1 to C.sub.8 alkyl substituted phenylamino, di C.sub.1 to C.sub.8 alkyl substituted phenylamino, naphthylamino or dinaphthylamino; R" is selected from the group consisting of C.sub.1 to C.sub.8 alkyl, phenyl, C.sub.1 to C.sub.8 alkyl substituted phenyl and naphthyl, which comprises reaction in an inert aprotic dipolar solvent a diazenedicarboxamide of the formula ##STR6## with an organosulfinic acid salt of the formula R"SO.sub.2 M wherein R, R' and R" is defined above and M is potassium, sodium, zinc or ammonium and recovering the sulfonyl dicarboxamide.
- 2. The process of claim 1 wherein said inert aprotic dipolar solvent is selected from the group consisting essentially of dimethylsulfoxide, dimethylformamide, tetrahydro-1,1dioxide, tetramethyl urea, hexamethylphosphoryl triamide and mixtures thereof.
- 3. The process of claim 1 wherein R" is aromatic sulfinate selected from the group consisting essentially of phenyl, tolyl and naphthyl.
- 4. A process for the manufacture of sulfonyl dicarboxamides of the formula ##STR7## wherein R and R' may be the same or different and are C.sub.1 to C.sub.8 alkylamino, di C.sub.1 to C.sub.8 alkylamino, phenylamino, diphenylamino, C.sub.1 to C.sub.8 alkyl substituted phenylamino, di C.sub.1 to C.sub.8 alkyl substituted phenylamino, naphthylamino or dinaphthylamino; R" is selected from the group consisting of C.sub.1 to C.sub.8 alkyl, phenyl, C.sub.1 to C.sub.8 alkyl substituted phenyl and naphthyl, which comprises reacting in water a diazenedicarboxamide of the formula ##STR8## with an organosulfinic acid salt of the formula R"SO.sub.2 M wherein R, R' and R" is defined above and M is potassium, sodium, zinc or ammonium and recovering the sulfonyl dicarboxamide.
- 5. Sulfonyl dicarboxamides of the formula ##STR9## wherein R and R' are the same or different and are selected from the group consisting of C.sub.1 to C.sub.8 alkylamino, di C.sub.1 to C.sub.8 alkylamino, phenylamino, diphenylamino, C.sub.1 to C.sub.8 alkyl substituted phenylamino, naphthylamino, and dinaphthylamino; and R" is selected from the group consisting of C.sub.1 to C.sub.8 alkyl, phenyl, C.sub.1 to C.sub.8 alkyl substituted phenyl and naphthyl.
- 6. The 1,2-diazanedicarboxamide of claim 5 wherein R and R' are the same and are selected from the group consisting of dimethylamino and phenylamino.
- 7. The process of claim 4 wherein said inert aprotic dipolar solvent is selected from the group consisting essentially of dimethylsulfoxide, dimethylformamide, tetrahydrothiophene-1,1 dioxide, tetramethyl urea, hexamethylphosphoryl triamide and mixtures thereof.
- 8. The process of claim 4 wherein R" is aromatic group selected from the group consisting essentially of phenyl, tolyl and naphthyl.
