Structures are assigned to the so-called “3-methylanthranil dichloride” and “x-chloro-3-methylanthranil”. Nitration of anthranils gives mainly the 5-substituted derivatives.

Dibenzoylfuroxan (I) reagiert mit Phenylacetylen (II) uber (III)-(V) zum Isoxazol-nitril (VI).

Furazan N-oxides with a strained ring bridging the 3- and 4-positions are progressively deoxygenated by trialkyl phosphites, forming furazans, which can in some cases be isolated, and dinitriles. Heating in the presence of an acetylene forms bis(nitrile oxide) adducts (isoxazoles), with the more highly-strained types.

Nuclear magnetic resonance (1H) at room and elevated temperatures has been used to study the tautomerism of a number of naphtho- and quinolino-furoxans. Free-energy differences between tautomers are, in general, small, while the activation energies for their equilibrations (ca. 20 kcal./mole) are ca. 6 kcal./mole higher than those of benzofuroxans. An attempt to prepare naphtho[2,3-c]furoxan was unsuccessful.
