Decomposition of azidothiophenes (3) gives the thieno[3,2-c][1λ4, 2]thiazines (4), which are stable cyclic sulphimides, the ylidic nature of (4a) being confirmed by its properties and X-ray structure determination; photolysis of the sulphimides (4) gives the thieno[3,2-b]pyrroles (6) suggesting that MeS and PhS undergo very rapid [1,5] sigmatropic shifts.
azidothiophenes的分解(3)给出了噻吩并[3,2- c ^ ] [1λ 4,2]噻嗪类(4),其是稳定的环状sulphimides,(的ylidic性质4A)由它的属性,并确认X射线结构决心; 硫化亚胺(4)的光解得到噻吩并[3,2- b ]吡咯(6),这表明MeS和PhS经历了非常快的[1,5]σ位移。
