Intramolecular reductive coupling reaction of a series of diketones 1 and dioxo sulfides 3 induced by a low-valent titanium reagent at reflux in tetrahydrofuran affords 1,2-diheteroarylcycloalkenes 2 and 3,4-diheteroaryl-substituted 2,5-dihydrothiophenes

A class of 3,4-diarylthiophenes was prepared in excellent yield (80-91%) by oxidation of 3,4-diaryl-2,5-dihydrothiophenes with CuBr2. The approach is also available for the synthesis of 3,4-diarylpyrroles and 3,4-diarylfuran. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
