In 2022,Fu, Jiayue; Li, Bingbing; Wang, Xiugui; Liang, Qida; Peng, Xiaoshi; Yang, Lu; Wan, Tao; Wang, Xinxiu; Lin, Bin; Cheng, Maosheng; Liu, Yongxiang published an article in Chinese Journal of Chemistry. The title of the article was 《Au(I)-Catalyzed 6-endo-dig Cyclizations of Aromatic 1, 5-Enynes to 2-(Naphthalen-2-yl)anilines Leading to Divergent Syntheses of Benzo[α]carbazole, Benzo[c,h]cinnoline and Dibenzo[i]phenanthridine Derivatives》.SDS of cas: 63069-48-7 The author mentioned the following in the article:
A gold(I)-catalyzed 6-endo-dig cyclization of aromatic 1,5-enynes was developed to synthesize 2-(naphthalen-2-yl)anilines. The functional group tolerance of this cyclization was examined systematically and a possible mechanism was proposed. The derivatization of 2-(naphthalen-2-yl)aniline was carried out to facile access to benzo[α]carbazole, benzo[c,h]cinnoline and dibenzo[i]phenanthridine derivatives in a divergent way. The experimental process involved the reaction of 4-Chloro-2-iodoaniline(cas: 63069-48-7SDS of cas: 63069-48-7)
4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.SDS of cas: 63069-48-7
