The reaction of S4N4 with cyano- and trifluoromethyl-substituted alkynes gives trithiadiazepines (1b-d) in good yield; with less reactive alkynes the yields of trithiadiazepines (1) are greatly improved by titanium(IV) chloride catalysis, making a range of functional derivatives of this ring system readily available.
S 4 N 4与氰基和三氟甲基取代的炔烃反应生成三噻二氮杂卓(1b - d),收率良好;在反应性炔烃较少的情况下,通过氯化钛(IV)催化可大大提高三噻二氮杂((1)的收率,从而使该环体系的一系列功能衍生物容易获得。

S4N4 with dimethyl acetylenedicarboxylate include the trithiadiazepine (5) and the trithiatriazepine (6) whose planar structures, determined by X-ray diffraction, represent two new stable 10π electron aromatic ring systems; these structures correct previous assignments.
S 4 N 4与乙炔二甲酸二甲酯的反应产物包括三噻二氮杂(5)和三硫杂氮杂(6),它们的平面结构由X射线衍射确定,代表了两个新的稳定的10π电子芳环体系。这些结构可以更正先前的分配。
