Notes:
The 13C n.m.r. spectrum of benzofuroxan at -15°C is assigned on the basis of selective decoupling experiments and by comparison with the 13C chemical shifts of model compounds. The 13C spectra were also measured in trifluoroacetic acid as a solvent. From the temperature dependence of the 13C spectrum of benzofuroxan in CDCl3, a barrier of 14·0 ± 0·2 kcal mol-1 is obtained for the degenerate tautomerism in this compound.
