N 2-[1-(1-Adamantyl)alkyl]naphthalene-1,2-diamines reacted with benzoyl chlorides in chloroform in the presence of triethylamine to give N-2-[1-(1-adamantyl)alkylamino]naphthalen-1-yl}benzamides which underwent intramolecular cyclization to 2-aryl-3H-naphtho[1,2-d]imidazoles on heating in toluene in the presence of p-toluenesulfonic acid. 3-[(1-Adamantyl)methyl]-2-(3-nitrophenyl)-3H-naphtho[1,2-d]imidazole
Ñ 2 - [1-(1-金刚烷基)烷基]萘-1,2-二胺与苯甲酰氯的氯仿,在三乙胺的存在下反应,得到ñ - 2- [1-(1-金刚烷基)烷基氨基]萘在对甲苯磺酸存在下在甲苯中加热时,将1-基}苯甲酰胺分子内环化为2-芳基-3 H-萘[1,2- d ]咪唑。由N 2 -[(1-金刚烷基)甲基]萘-1,2合成3-[(1-金刚烷基)甲基] -2-(3-硝基苯基)-3 H-萘[1,2- d ]咪唑-二胺和3-硝基苯甲醛。
