Cyanomethanesulphonyl chloride has been prepared, and some aspects of its chemistry have been investigated. Reactions with primary and secondary amines led to the expected sulphonamides, but sulphonates derived from reactions with alcohols were in most cases too unstable to be isolated. Reactions with enamines gave either substituted thietan 1,1-dioxides or acyclic sulphones, depending upon whether the enamine was derived
制备了氰甲磺酰氯,并对其化学性质进行了一些研究。与伯胺和仲胺的反应生成了预期的磺酰胺,但是在大多数情况下,与醇反应衍生的磺酸盐不稳定,无法分离。与烯胺的反应根据烯胺是衍生自醛还是环状酮而得到取代的1,1-二氧化噻吨或无环砜。衍生自氰基甲磺酰氯的磺酰胺含有酸性亚甲基,并且发现它们以常规方式与醛和亚硝酸异戊酯缩合,分别得到取代的烯烃和肟。然而,与重氮盐的偶联反应过程是,似乎取决于磺酰胺是衍生自伯胺还是仲胺。与母体化合物相比,具有连接至α-碳原子的烷基的氰基甲磺酰氯的同系物对亲核试剂的反应性显着降低,反应性随链长的增加而降低。从每个同系物制备许多磺酰胺。
