acid give tetralin-2-ones analogous to that formed from 1-chloro-2-naphthol. 1,6-Di-t-butyl-2-naphthol, however, gives only 1,6-di-t-butyl-1,3-dichloro-1,2-dihydronaphthalene; 1-iodo-2-naphthol gives some 1,1,3,4-tetrachlorotetralin-2-one in acetic acid, whereas in chloroform it gives a mixture from which r,-1,c-2,t-3,t-4,5,7-hexachlorotetralin-6-ol was isolated.

用过量的氯在乙酸中氯化1-甲基-2-萘酚,1-溴-2-萘酚,2,2'-二羟基-1,1'-二萘甲甲烷和6-叔丁基-2-萘酚得到类似于由1-氯-2-萘酚形成的四氢萘-2-酮。然而,1,6-二叔丁基-2-萘酚仅产生1,6-二叔丁基-1,3-二氯-1,2-二氢萘;1-碘-2-萘酚给出了一些1,1,3,4- tetrachlorotetralin -2-酮在乙酸,而在氯仿它给出了一个从混合物其中[R,-1,Ç -2,吨-3,吨-分离出4,5,7-六氯四氢萘-6-ol。讨论了这些产品的结构及其产生的途径。
