Reaction of hydrazidoyl halides 1-5 with potassium selenocyanate in ethanol produces the corresponding 2,4-disubstituted-5-imino-Δ2-1,3,4-selenadiazolines, 9-13 respectively.Nitrosation of the latter yields the N-nitroso derivatives 14-17, which decompose upon refluxing in xylene to give 2,4-disubstituted Δ2-1,3,4-selenadiazolin-5-ones in good yield.Compounds 9-13 give the respective N-acetyl derivatives 22-26 and N-benzoyl derivatives 27-31 with acetic anhydride and benzoyl chloride in pyridine.
