Abstract:
The [4+2] cycloaddition products between thiobenzophenone (1) and arylalkenes (2) were obtained in the presence of (thia)pyrylium salts (sensitizer=3 or 4) as electron transfer photosensitizers. Although both radical cations 1*+ and 2*+ are generated, only the former is involved in the process.
