2-addition to olefins, acetylenes, and by the formation of products apparently arising from radical abstraction. Addition to dimethyl azodicarboxylate gave dimethyl 1,2-dihydrobenz[cd]indazole-1,2-dicarboxylate, an example of the elusive benz[cd]indazole system.
1-氨基萘并[1,8- de ]三嗪的氧化反应生成的1,8-脱氢萘是一种高反应性物质,可通过将1,2-加成至烯烃,乙炔中以及形成明显的产物而被捕集从根本抽象。加到偶氮二羧酸二甲酯中,得到1,2-二氢苯并[ cd ]吲唑-1,2-二羧酸二甲酯,这是难以捉摸的苯并[ cd ]吲唑体系的例子。

Amination of naphtho[1,8-de]triazine with aqueous hydroxylamine-O-sulphonic acid gives 1-aminonaphtho-[1,8-de]triazine and 1-amino-8-azidonaphthalene. Amination with ethereal chloramine gives 1- and 2-aminonaphthotriazines and the latter was shown to rearrange to the amino-azide under the conditions of the hydroxylamine-O-sulphonic acid amination. Both 1 - and 2-aminotriazines are rearranged smoothly
用羟胺-O-磺酸水溶液胺化萘[1,8- de ]三嗪,得到1-氨基萘-[1,8- de ]三嗪和1-氨基-8-叠氮基萘。用醚化氯胺胺化得到1-和2-氨基萘三嗪,并且显示后者在羟胺-O-磺酸胺化的条件下重排成氨基叠氮化物。1-和3-氨基三嗪均被酸平滑地重排至氨基叠氮化物。将这些三嗪的稳定性与相关三唑的稳定性进行了比较,并提出了其重排的机理。

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。

reactivities of 1,8-dehydronaphthalene (1) to cyclicpolyenes, i.e., cycloheptatriene, cyclopentadiene, 6,6-dimethylfulvene, furan, and norbornadiene, were examined. It was found that the C–H insertion reaction at the end of the conjugated systems, a new type of reaction of 1, as well as the 1,2-cycloaddition reaction occurs in every conjugatedcyclicpolyene. A stepwise mechanism for the formation
