## Abstract magnified image Efficient route to 5βacylβ2βsubstitutedβ1,2,3βtriazolβ4βamines __via__ reaction of 3βoxoβ2β(arylhydrazono)βpentanenitrile with hydroxylamine hydrochloride is reported. Xβray crystal structure has been made to confirm the structure of reaction products.
1,4-Disubstituted 5-thioxoperhydroimidazo [4,5-d]imidazol-2-ones were prepared by one-pot criss-cross cycloaddition reactions of 1,4-disubstituted 1,4-diazabuta-1,3-dienes with HNCS and HNCO generated in situ from potassium salts by acetic acid.
