Thio- and selenopyrylium salts undergo simultaneous oxidation, leading to the corresponding benzoylselenophene or benzoylthiophene, and reduction reactions leading to 4H-selenopyran or 4H-thiopyran In the presence of water and triethylamine .

2-Aroyl-3,5-diarylthiophenes were prepared in very good yields by reaction of 2,4,6-triarylpyrylium salts or 2,4,6-triarylthiopyrylium salts with an aqeous solution of sodium sulfide and iodine at room temperature.

We have studied the oxidation of 4H-chalcogenopyrans and chalcogenopyrylium salts by lead tetraacetate. We have established that the major reaction products on oxidation of 2,6-diphenyl-4H-thiopyran and selenopyran are 2,6-diphenyl-4H-thio(seleno)pyran-4-
