The reaction of carbondisulphide with 1,8-dehydronaphthalene, generated by oxidation of 1-amino-1H-naphtho-[1,8-de]triazine (7), gave naphtho[1,8-bc]thiet (10)(6–8%), naphtho[1,8-de]-1,3-dithiin-2-thione (11)(3–5%), naphtho [1,8-bc]thiophen-2-thione (12)(4–5%), and naphthol [1,8-bc]thiophen-2-one (13)(4–5%). The results can be explained by radical addition of 1,8-dehydronaphthalene to the sulphur
1-氨基-1 H-萘-[1,8- de ]三嗪(7)的氧化生成二硫化碳与1,8-脱氢萘的反应,得到萘[1,8- bc ] thiet(10) (6-8%),萘并[1,8- de ] -1,3-二硫-2--2-硫酮(11)(3-5%),萘并[1,8 - bc ]噻吩-2-硫酮(12 )(4-5%)和萘酚[1,8- bc ]噻吩-2-酮(13)(4-5%)。可以通过将1,8-脱氢萘自由基加成到二硫化碳的硫原子上形成新的1,5-二自由基中间体(8)来解释其结果,由此可以得出最终产物。

In order to discover newelectrondonors for conducting charge-transfer complexes, the four title compouds 1–4 composed of two heterocycles have been prepared via 1,8-dichalcogen-bridged naphthalene. The cyclic voltammetery indicates that symmetrical 1 and 2 are poor donors, but unsymmetrical 3 and 4 possess considerable donor abilities. The latter compounds are thus capable of forming some crystalline

With a view to discovering new electron donors for low-dimensionally metallic materials, the title compounds were prepared via the corresponding 1,8-dichalcogen-bridged naphthalenes. Their donor characters were examined by cyclic voltammetry, as compared with those of the reference compounds.
