Abstract
Oxidation of 2,5-disubstituted thiophenes and benzothiophenes by H2O2 in CF3CO2H-CH2Cl2 appears a convenient method to access the correspond ing reactive sulfoxides; it is used to prepare 2,5-diphenylthiophene-1 -oxide, which is the first thiophene oxide to be fully structurally ch aracterised crystallographically and the nonplanar structure of the th iophene ring is established; formation of an unexpected dehydrogenated dimer of this sulfoxide is also observed.
