Abstract A novel, visible-light-mediated method for the synthesis of 2-sulfenylindenones from easily available thiophenols (2.0 equiv.) and 1, 3-diarylpropynones (1.0 equiv.) in the presence of eosin Y (0.02 equiv.) under air atmosphere has been developed. The reaction proceeded smoothly, for a wide range of derivatives of thiophenols and 3-diarylpropynones, to give the expected products in moderate
摘要 一种新的可见光介导的方法,用于在空气中,在曙红 Y(0.02 当量)存在下,由易得的苯硫酚(2.0 当量)和 1, 3-二芳基丙炔酮(1.0 当量)合成 2-亚磺基茚酮气氛已经形成。反应进行得很顺利,对于广泛的苯硫酚和 3-二芳基丙酮衍生物,以中等至良好的收率得到预期的产物。与传统方法相比,该方法更方便,避免使用化学计量的 I2 和 K2S2O8。图形概要
