title: TFA-promoted direct C-H sulfenylation at the C2 position of non-protected indoles.
abstract: 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.
