Abstract
Photochemical electron transfer (PET) reactions were carried out using PET sensitizer (TPT) and dichalcogenides (DPDT/DPDS). Sensitizer fluo rescence quenching by dichalcogenides is found to be very efficient an d it leads to the electron-transfer process. A phenylchalcogenide cati on produced via dichalcogenide radical cation, was successfully utiliz ed in cyclization reactions using variety of substrates. Thermal cycli zation reaction supports the PET mechanism and also indicates the pote ntiality of the method in organic synthesis. (C) 1998 Elsevier Science S.A. All rights reserved.
