Preparation of substituted pyridazines
-
, (2008/06/13)
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° to 80° C. in an aqueous solvent system and mineral acid. The substituted pyridazines are useful as intermediates to herbicidal and fungicidal compounds.
