ABSTRACT:
A novel process is described for preparing substituted pyridazines, where a less substituted pyridazine is reacted with a carboxylic acid in the presence of a silver ion as catalyst, using peroxydisulfate ion. The reaction is run at a temperature from about 40.degree. to 80.degree. C. in an aqueous solvent system and mineral acid. The substituted pyridazines are useful as intermediates to herbicidal and fungicidal compounds.
