N-Aryl nitrile imines bearing a thioether function in the ortho-position were generated in situ on treating the corresponding hydrazonyl chlorides with triethylamine in boiling benzene. In all cases, the major products were 4,1,2-benzothiadiazines arising from intramolecular participation of the sulphur and subsequent evolution of transient cyclic ylides. Minor products due to an intramolecular 1,3-dipolar
在沸腾的苯中用三乙胺处理相应的酰肼基氯化物时,原位生成在邻位具有硫醚功能的N-芳基腈亚胺。在所有情况下,主要产物均为4,1,2-苯并噻二嗪,其产生于硫的分子内参与和随后的环状瞬态逸出。有时会由于分子内1,3-偶极环加成反应而获得次要产物。
