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.
## Abstract Thermal rearrangement of 3βacylisoxazole arylhydrazones allowed facile preparation of 2__H__β1,2,3βtriazoles which were firstly reacted with isoamyl nitrite and then with an opportune arylhydrazine to produce the corresponding Ξ±βhydroxyiminohydrazones **8aβh**. The reaction of compounds
