    Abstract: Originally issued as Basic No. 58387 U-E in Week U 40. Pyridazinium salts are converted by transferring a neutral pyridazine deriv. which is the basis of the starting pyridazinium salt, from an aq. soln. of the starting pyridazinium salt into the org. phase by addn. of bases and simultaneous extraction with an org. solvent which is water-immiscible or only difficultly miscible with water; sepg. the aq. phase; admixing the org. phase with an acid contg. the desired anion; and isolating the resulting pyridazinium salt in known manner.

    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.
