用金属氧化物在分子氧（o2）作用下氧化了3种4-甲氧基萘胺4a-c。4-甲氧基-1-萘胺4a和4,6-二甲氧基-1-萘胺4b在o2作用下主要生成2-氨基-1,4-萘醌衍生物5a和5b，而4,8-二甲氧基-1-萘胺4c主要生成独特的咔唑6c。
Three types of 4-methoxynaphthylamines 4a-c were oxidized by treatment with metal oxides under molecular oxygen (O 2 ). 4-Methoxy-1-naphthylamine 4a and 4,6-dimethoxy-1-naphthylamine 4b, on treatment with TiO 2 under O 2 , gave mainly 2-amino-1,4-naphthoquinone derivatives 5a and 5b, respectively whereas 4,8-dimethoxy-1-naphthylamine 4c afforded an unique carbazole 6c as the major product.
