Nucleophilic substitution on perchlorindane (1) with ethoxide ion gives nonachloro-5-ethoxyindane (6), heptachloro-1,1,5-triethoxyindane (7), and 3,5,6-trichloro-4-ethoxy-2-trichlorovinylbenzoic acid (8). The results show that in perchloroindane (1) aromatic chlorines are more susceptible to substitution than aliphatic chlorines. Since this has not previously been realised, structures of the products
在全氯茚满(1)上用乙醇酸离子进行亲核取代,得到九氯-5-乙氧基茚满(6),七氯-1,1,5-三乙氧基茚满(7)和3,5,6-三氯-4-乙氧基-2-三氯乙烯基苯甲酸(8)。结果表明,在全氯茚满(1)中,芳族氯比脂族氯更易于取代。由于以前尚未实现,因此文献中给出的乘积(6),(7)和(8)的结构不正确。从这些产品中,合成了以下新化合物:五氯-5-羟基茚满-1,3-二酮(9),五氯-5-乙氧基茚满-1,3-二酮(10),七氯-5-乙氧基茚满-1-一(11),七氯-5-羟基茚满-1-酮(12)及其钠盐(13),2-溴六氯-5-羟基苯乙烯(14),2-溴六氯-5-甲氧基苯乙烯(15),3,5,H-茚-1-酮(17),五氯-5-甲氧基-1 H-茚-1-酮(18),5,7,8-三氯-6-乙氧基异色满-1,4-二酮(19), 5,6,8-三氯-7-乙氧基异色满-1,4-二酮(20),三氯-4-乙氧基邻苯二甲酸(21)及其酸酐(22),2
