Abstract:
A process for preparing a sulfonylaminocarbonyl triazolinone or a salt thereof, comprising the steps of:a) reacting a substituted triazolinone of the following general formula (I) ##STR20## wherein R.sup.1 and R.sup.2 each represents an unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl radical,with a sulfonyl isocyanate of the following general formula (II)O.dbd.C.dbd.N--SO.sub.2 --R.sup.3 (II)whereinR.sup.3 represents an unsubstituted or substituted alkyl, aryl, arylalkyl or heteroaryl radical,to produce a sulfonylaminocarbonyl triazolinone intermediate product of the general formula (III) ##STR21## wherein R.sup.1, R.sup.2, and R.sup.3 are as defined above, and b) reacting the intermediate product under pH controlled conditions with a base to produce a salt thereof, a final product of the general formula (IV) ##STR22## wherein R.sup.1, R.sup.2, and R.sup.3 are as defined above, and M represents an alkali or alkaline earth metal, or protonated ammonia derivative.
