Synthesis of 5-(Substituted Phenyl) 4-Acetyl-2-methylthio-Δ2-1,3,4-thiadiazolines and their Oxidation with Potassium Permanganate
The reaction of aldehyde methylthio(thiocarbonyl)hydrazones (2) with acetic anhydride or acetyl chloride gave 5-(substituted phenyl) 4-acetyl-2-methylthio-Δ2-1,3,4-thiadiazolines (3).Oxidation of compounds (3) with potassium permanganate in ace
