| Abstract: | Unexpectedly, nitrosation of 5,7‐dialkyl‐3‐thioxoperhydroimidazo4,5‐e]‐1,2,4‐triazine‐6‐ones(thiones) with sodium nitrite in glacial AcOH led to 3,3′‐bis(5,7‐dialkyl‐1‐nitroso‐6‐oxo(thioxo)‐1,4,4a,5,7,7a‐hexahydroimidazo4,5‐e]‐1,2,4‐triazinyl)disulfides that decomposed spontaneously into 1,3‐dialkyl‐5‐thioxohexahydroimidazo4,5‐d]imidazol‐2(1H)‐ones(thiones) in DMSO‐d6 in the presence of water. |
