Strong-field ionization of complex molecules [PDF]
Phys. Rev. Research 3, 013089 (2021), 2020 Strong-field photoelectron momentum imaging of the prototypical biomolecule indole was disentangled in a combined experimental and computational approach. Experimentally, strong control over the molecules enabled the acquisition of photoelectron momentum distributions in the molecular frame for a well-defined, narrow range of incident intensities.

Photophysics of indole upon x-ray absorption [PDF]
Physical Chemistry Chemical Physics, 2018, 20, 20205 - 20216, 2018 A photofragmentation study of gas-phase indole (C$_8$H$_7$N) upon single-photon ionization at a photon energy of 420 eV is presented. Indole was primarily inner-shell ionized at its nitrogen and carbon $1s$ orbitals. Electrons and ions were measured in coincidence by means of velocity map imaging.

Chemoselective N-acylation of indoles using thioesters as acyl source
Beilstein Journal of Organic Chemistry, 2022 The selective acylation of indoles often requires sensitive and reactive acyl chloride derivatives. Here, we report a mild, efficient, functional group tolerant, and highly chemoselective N-acylation of indoles using thioesters as a stable acyl source. A

Electrochemical Dearomative 2,3-Difunctionalization of Indoles.
Journal of the American Chemical Society, 2018 We report the use of electrochemistry to perform a direct oxidative dearomatization of indoles leading to 2,3-dialkoxy or 2,3-diazido indolines under undivided conditions at a constant current. This operationally simple electro-oxidative procedure avoids
