Peroxydichloromaleic acid

Other peroxides such as fert-butyl hydroperoxide [226, 227], performic acid 247, 248], peroxytrifluoroacetic acid [/55], peroxydichloromaleic acid [339], and dimethyldioxirane [210] are used less frequently. [Pg.237]

Pyridazines are oxidized to mono-N-oxides by peroxydichloromaleic acid prepared in situ from 90% hydrogen peroxide and dichloromaleic anhydride (equation 507) [339]. [Pg.239]

N-Oxidation of pyridazine with hydrogen peroxide and in the presence of sodium tungstate gives the JV-oxide in low yield. Peroxydichloromaleic acid is an efficient reagent for the preparation of pyridazine JV-oxides and polyhalogenated pyridazines are best N-oxidized with a mixture of hydrogen peroxide, concentrated sulfuric acid, and acetic acid or trifluoro-acetic acid. Some 3-aminopyridazines were transformed in a single... [Pg.397]
