Abstract
Process for the preparation of pyridazoic derivatives of herbicidal effect of general formula ** (See formula) ** wherein R represents hydrogen or a cycloalkyl radical or phenyl, optionally substituted, R 1 represents a saturated or unsaturated lower alkyl radical and optionally substituted by chloro, or a phenyl or aralkyl radical, optionally substituted, or a cycloalkyl radical, or radical of tetrahydrofuran, benzothiazole or acetic acid, and R2 has the same meanings as R1, where R1 and R2 may be the same or different, characterized in that a derivative of 4,5-dichloropyridazone is reacted with organic compounds containing sulfur.
