    Abstract: 1-Subst-4-amino-6-pyridazones with herbicidal activity Title cpds. are 1-R-4-X-5-Y-6-pyridazones where R is phenyl or aralkyl (opt. subst. by halogen, alkyl, alkoxy or haloalkyl) or cyclohexyl (opt. subst by halogen, or alkyl), Y is H, halogen, alkoxy or mercaptoalkyl and X is cyclopropanecarboxamido, (m-alkanoylaminophenoxy) carbonylamino, (m-alkoxycarbonylaminophenoxy)carbonylamino, N'-cycloalkyl-N'-hydroxy-ureido or N'-chlorosulphonyl-ureido; X can also be NH2 or acetamido when Y is H or is aralkyl. The cpds. may be prepd. by reacting corr. 4-isocyrindopyridazines with m-acylaminophenols or hydroxylamines, by reacting 4-aminopyridazones with chlorosulphonyl isocyanate or cyclopropanecarboxylic acid chloride, by reacting 4,5-dihalopyridazones with NH3, or by reacting 4-amino-5-chloropyridazones with hydrogen.
