1,2-DI(4-R-FURAZAN-3-YL)GLYOXIMES: SYNTHESIS BY THE REDUCTION OF 3,4-BIS(4-R-FURAZAN-3-YL)FUROXANS AND STUDY OF THE REACTIVITY OF THESE COMPOUNDS

Abstract
The reduction of 3,4-bis(4-R-furazan-3-yl)furoxans with hydrazine or hydrogen in the presence of palladium on carbon resulted in opening of the furoxan ring and formation of (Z,E)-dioximes of 1,2-di(4-R-furazan-3-yl)ethane-1,2-diones in high yield. The reactivity of the resultant glyoximes was studied.
