In the presence of BiCl3, the hydroarylation of styrenes with electron-rich arenes afforded Markovnikov adducts selectively in good to high yields. Under arene-free conditions, the intermolecular hydroarylation of α-substituted styrenes and subsequent intramolecular hydroarylation produced the cyclic dimers of α-substituted styrenes in good yields.

在 BiCl3 存在下,苯乙烯与富电子芳烃的加氢芳基化以良好到高产率选择性地提供马尔科夫尼科夫加合物。在无芳烃的条件下,α-取代苯乙烯的分子间加氢芳基化和随后的分子内加氢芳基化以良好的产率产生了α-取代苯乙烯的环状二聚体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
