1'-sulfinylbis(benzotriazole)/trimethylchlorosilane at 45-65 degrees C to form 1,2-di(benzotriazol-1-yl)-2-arylimino-1-ethanethiones 3a-e, while heating the same reagents at 110 degrees C results in dibenzo[b,h][1,4,7]thiadiazonines 5a,c,d, and 6. X-ray crystal structures are reported for three representative examples.
乙酰苯胺1a-e与1,1'-亚磺酰基双(苯并三唑)/三甲基氯硅烷在45-65摄氏度下反应形成1,2-二(苯并三唑-1-基)-2-芳基-1-乙硫酮3a-e,而在110℃下加热相同的试剂会生成二苯并[b,h] [1,4,7]噻二唑啉5a,c,d和6。报道了三个代表性实例的X射线晶体结构。
