obtained for the reaction of 3-methoxydehydrobenzene, generated from 2-amino-6-methoxybenzoic acid by aprotic diazotization, or from 2-bromo-3-methoxyphenyl toluene-p-sulphonate by treatment with butyllithium, and for the reaction of 3-(methoxycarbonyl)dehydrobenzene, generated from 2-amino-6-(methoxycarbonyl) benzoic acid by aprotic diazotization, with seven 2-substituted furans are recorded. These
由2-氨基-6-甲氧基苯甲酸通过非质子重氮化而生成的3-甲氧基脱氢苯的反应,或由2-溴-3-甲氧基苯基甲苯-对磺酸酯经丁基锂的处理而生成的3-甲氧基脱氢苯的反应的环加合物的异构体比,以及记录了由2-氨基-6-(甲氧羰基)苯甲酸经质子重氮化而生成的3-(甲氧羰基)脱氢苯与七种2-取代的呋喃的反应。将根据异步,协调一致的双自由基反应途径来讨论这些结果。
