Dioximes phosphine

The reduction of benzofuroxans can lead to a variety of products, depending upon the conditions. Deoxygenation to benzofurazans (40) can be effected either directly, using trialkyl phosphites, -tributyl or triphenyl - phosphine, or indirectly, via o-quinone dioximes (41), using methanol and potassium hydroxide, or hydroxyl-amine and alkali. - - The dioximes may be isolated, but... [Pg.21]

A valuable route to benzofurazans is provided by deoxygenation of the corresponding benzofuroxan. This may be accomplished either directly using trialkyl phosphites, tributyl-or triphe nyl-phosphine, or indirectly via the quinone dioxime using, for example, methanol and potassium hydroxide, hydroxylamine and alkali, sodium azide in DMSO or ethylene glycol, sodium borohydride, and occasionally thermolysis alone. More detailed discussion of these reactions is included in Section 4.22.3.2.4. [Pg.419]
