, p. 13898 - 13901 (2015)
A simple, efficient and practical metal-free C-H sulfenylation process at the C2 position of non-protected indoles has been developed. 2-Thioindoles were obtained in moderate to high yields using stable and readily available N-(thio)succinimides at room temperature in the presence of TFA.
Intramolecular Hydroamination of Selenoalkynes to 2-Selenylindoles in the Absence of Catalyst
Coelho, Felipe L.,Gil, Eduarda S.,Gon?alves, Paulo F. B.,Campo, Leandra F.,Schneider, Paulo H.

In this work, a series of 2-chalcogenylindoles was synthesized by an efficient methodology, starting from chalcogenoalkynes, including a previously unreported tellurium indole derivative. For the first time, these 2-substituted chalcogenylindoles were obtained in the absence of metal catalyst or base, under thermal conditions only. In addition, the results described herein represent a methodology with inverse regioselectivity for the chalcogen functionalization of indoles.
Synthesis of 2-(Arylthio)indolenines via Chemoselective Arylation of Thio-Oxindoles with Arynes
Saputra, Adi,Fan, Rong,Yao, Tuanli,Chen, Jian,Tan, Jiajing
, p. 2683 - 2688 (2020/05/18)
A chemoselective S-arylation reaction of thio-oxindoles with arynes is presented. The reaction was performed under mild conditions and provided a straightforward synthesis of 2-(arylthio)indolenines in good to excellent yields. Besides, this simple operat
