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, 69451 Weinheim, Germany, 2007)
通过用 CuBr2 氧化 3,4-二芳基-2,5-二氢噻吩,以极好的收率(80-91%)制备了一类 3,4-二芳基噻吩。该方法也可用于合成 3,4-二芳基吡咯和 3,4-二芳基呋喃。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
