## Abstract The first general synthetic route has been developed for the convenient preparation of iodofurazans. The approach was accomplished by oneβpot diazotizationβiodation reaction of appropriate aminofurazans. A combination of sodium nitrite and iodine in organic solvent under anhydrous condi
3-Amino-4-(thienyl-2)furazan (3) has been synthesized from 2-acetylthiophene (4) by several routes. Nitrosation of 4, followed by oximation of the resulting oxime salt 5, gave a 6:1 mixture of the E,E and E,Z isomers of thienylglyoxime (1). Estimation of differences and analogies of these isomers' r
