On August 20, 2021, Ou, Yifeng; Yang, Tianbao; Tang, Niu; Yin, Shuang-Feng; Kambe, Nobuaki; Qiu, Renhua published an article.Formula: C8H8ClN The title of the article was Photo-Induced N-N Coupling of o-Nitrobenzyl Alcohols and Indolines To Give N-Aryl-1-amino Indoles. And the article contained the following:
A novel method to synthesize N-aryl-1-amino indoles I [R = H, Me, Ph, etc.; R1 = H, 6-Me, 5-Cl, etc.; R2 = H, 4-F, 5-Br, etc.] was established by the photoinduced N-N coupling reaction. This protocol was operated by treatment of o-nitrobenzyl alcs. and indolines in the presence of TEAI and acetic acid with a 24 W UV light-emitting diode (LED) (385-405 nm) irradiation The products bearing an aldehyde group can be further transformed to fluorescent probes based on Rhodamine derivative, which shows a high specificity and sensitivity for Fe3+. The experimental process involved the reaction of 6-Chloro-2,3-dihydro-1H-indole(cas: 52537-00-5).Formula: C8H8ClN
The Article related to aryl amino indole preparation, nitrobenzyl alc indoline photo induced coupling, Heterocyclic Compounds (One Hetero Atom): Indoles, Indolizines, Carbazoles, and Other Arenopyrroles and other aspects.Formula: C8H8ClN
