Synthesis and Synthetic Application of Chloro- And Bromofuroxans

Furoxans are potentially useful heteroaromatic units in pharmaceuticals and agrichemicals. However, the applications for furoxan-based compounds have been hampered due to the underdevelopment of their synthetic methods. Herein, we report a new synthetic approach for the synthesis of chloro- and bromofuroxans. The starting materials were dichloro- and dibromofuroxans, and the substituents were directly introduced to the furoxan ring in a modular fashion. The synthesized monohalofuroxans served as substrates for the installation of a second substituent to prepare further functionalized furoxans.

Unsymmetrically Substituted Furoxans. VII (1). 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.
