Unsymmetrically substituted furoxans. VII. A 13C NMR study of a series of isomeric pairs of furoxans and the structure of the two isomeric chloro‐phenyl‐furoxans

The structure of two isomeric chloro(phenyl)furoxans is proposed by comparison of their 13C nmr spectra with those of several unsymmetrically substituted furoxans and related furazans.
