A metal-free approach to N-aryl thioamides fromBuntesalts and anilines in DMSO has been developed. This method tolerated a wide range of functional groups on the aromatic ring, providing an ideal way to N-aryl thioamides in good to excellent yields from cheap and easily available starting materials. A plausible mechanism was also proposed based on the X-ray single crystal diffraction, NMR and MS

phenalenyl-based organic photocatalyst toward photoelectrochemical intramolecular C–S bond construction reactions under mild conditions. This phenalenyl core, which contains a vacant NBMO, acts as an electron reservoir, thereby facilitating the formation of a contact ion pair with electron-rich organic systems through intramolecular electron transfer under photoexcitation and aiding in catalytic regeneration
