Unsymmetrically substituted furoxans. Part 6. 3-Nitro-4-phenylfuroxan: reaction with sodium methoxide and X-ray structural analysis

Abstract

The reaction of sodium methoxide with the by-product obtained by the action of an excess of 85% hydrogen peroxide in trifluoroacetic acid on 3-amino-4-phenylfuroxan suggests, for this derivative, the 3-nitro-4-phenylfuroxan structure. X-Ray analysis confirms this deduction.
