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-

Oxidation of 2,4,6-triphenyl-4H-pyran, 2,4,6-triphenyl-4H-thiopyran, and 2,4,6-triphenyl-4H-selenopyran with lead tetraacetate yields, respectively, 2-benzoyl-3,5-diphenylfuran, 2-benzoyl-3,5-diphenylthiophene, and 2-benzoyl-3,5-diphenylselenophene.

The oxidation of 4H-4R-2,6-diphenylselenopyrans was studied.This reaction was found to depend on the presence of substituents at C(4) of the heterocycle and the reaction conditions.
OXIDATION OF 2,4,6-TRIARYL-4H-THIO(SELENO)PYRANS WITH SELENIUM DIOXIDE

, p. 632 - 634 (2007/10/02)
The oxidation of 2,4,6-triaryl-4H-thio(seleno)pyrans with selenium oxide in pyridine was studied.It is shown that the corresponding 2,4-diaryl-5-aroylthiophenes and -selenophenes are formed as a result of the oxidation.
