Oxidation of 2,5-disubstituted thiophenes and benzothiophenes by H2O2 in CF3CO2H-CH2Cl2 appears a convenient method to access the corresponding reactive sulfoxides; it is used to prepare 2,5-diphenylthiophene-1-oxide, which is the first thiophene oxide to

The oxidation of 2,5-diphenylfuran (1) with (hexamethylphophoramide)oxodiperoxomolybdenum(VI), MoO5*HMP, gave cis-1,4-diphenyl-2-butene-1,4-dione (2) and its cis-epoxide 3. 2,3-Diphenylpyrrole (4) was similarly treated with MoO5*HMPA to give the dimeric product 6, together with the cis-epoxide 3 and the trans-olefin 5.In the case of 2,5-diphenylthiophene (8), the oxidation with MoO5*HMPA occurred at the sulfur atom of 8 to give thiophene 1,1-dioxide (9).The oxidation of benzofuran (10) and benzothiophene (16) with MoO5*HMPA is also described.Keywords: furan; pyrrole; thiophene; benzofuran; benzothiophene; peroxomolybdenum complex; oxidation; epoxidation; dimerization
