Abstract Thermolysis of 4,5‐dinitroveratrole 1a in the presence of sodium azide and dimethylsulfoxide gives the new 5,6‐dimethoxybenzofuroxan, 2a , whereas 3,4,5‐trinitroveratrole led to the new 5(7),6‐dimethoxy‐4‐nitrobenzofuroxans 2e, 3e via a nucleophilic substitution of a nitro group by azide ion and pyrolytic ring closure. This method provides a simpler route to the known 1,3‐benzodioxano[5,6‐ c ]furoxan, 2b and 1,4‐benzodioxano[6,7‐ c ]furoxan 2c , as well.

The preferential solvation parameters, that is, the difference between the local and bulk mole fractions of the solvents in solutions of some structurally related sulfonamides in 1,4-dioxane + water binary mixtures are derived from their thermodynamic properties by means of the inverse Kirkwood-Buff integrals method. From solvent effect studies, it was found that all the sulfonamides considered were very sensitive to solvation effects, so the preferential solvation parameter, δxD,S, was negative in ...

In the title compound, C(16)H(13)NO(2), the two benzene rings make a dihedral angle of 55.5 (2)°. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.595 (3)Å], linking the mol-ecules into ladders of inversion dimers.
