                                    Treatment of 6-bromotrithiadiazepine (1) with Hünig's base in the presence of diaryldiazomethanes (2) gives the trithiadiazepyne cycloadducts (3) which undergo a deep-seated thermal rearrangement to give fused 1,2,3-dithiazoles (4), for which a mechanism is proposed.
                                    6- bromotrithiadiazepine(处理1)与Hunig氏碱中diaryldiazomethanes的存在下(2)给出trithiadiazepyne cycloadducts(3),其经过深层热重排,得到稠合的1,2,3- dithiazoles(4),为此提出了一种机制。
