Abstract

Process for the preparation of pyridazine-1-oxides of the general formula: ** (see formula) ** Wherein b'and b "signify either hydrogen atoms or together a 1,3-butadienylene- (1,4) residue, optionally substituted, r' signifies hydrogen or an alkyl radical or a phenyl radical, given case substituted, r means a hydrogen atom or a lower alkyl radical, the symbols alk lower alkylene radicals, which separate the oxygen atoms by at least 2 carbon atoms, and n means an integer from 2 to 9, characterized in that the pyridazines of formula are N-oxidized ** (see formula) ** Wherein b', b'', r', r, alk and n have the meanings indicated above or the compounds of formulas ** (see formula) ** They react directly or stepwise with each other, in which x and y are dissociable residues during the reaction leaving a vinylene- (l-2) bridge of formula ** (see formula) ** And b', b'', r', r, alk and n have the indicated meanings, or the compounds of formulas ** (see formula) ** They are reacted with each other, in which b', b'', r', r, alk and n have the indicated meanings and x'and y' are dissociable residues during the reaction leaving an etheric bridge -o-, or they are nitrated the compounds of formula ** (see formula) ** Where b', b'', r', r, n and alk have the indicated meanings.
