摘要:
Novel processes for producing 2-tert.-butyl-4,5-dichloro--3(2H)-pyridazinone comprise reacting tert. -butylhydrazine with mucochloric acid in an aromatic hydrocarbon and/or chlorinated hydrocarbon solvent. A novel compound, mucochloric acid-tert.-butylhydrazone, is also provided as an intermediate product.
