Aromaticketones were efficiently prepared in good yields by the reactions of aryl bromides with n-BuLi, followed by the reactions with aromaticaldehydes or aliphatic aldehydes and the subsequent treatment with molecular iodine and K2CO3, in a one-pot method. The same treatment of arenes, instead of aromatic bromides, also provided the corresponding aromaticketones in good yields. Using these methods
通过一锅法,通过芳基溴化物与n- BuLi的反应,然后与芳族醛或脂族醛的反应,以及随后用分子碘和K 2 CO 3的处理,可以有效地以高收率高效地制备芳族酮。芳烃的相同处理而不是芳族溴化物也以良好的产率提供了相应的芳族酮。使用这些方法,可以通过简单,无过渡金属且因此对环境无害的实验程序有效地制备各种带有富电子芳族化合物和缺电子芳族化合物的二芳基酮和烷基芳基酮。

Catalytic enantioselective construction of optically active tetraarylmethanes remains a challenging issue in the field of asymmetric synthesis because of the overwhelming steric hindrance and formidable stereocontrol that existed in construction of the all-aryl-substituted quaternary carbon stereocenter. Here, we reported an organocatalytic asymmetric synthesis of chiral tetraarylmethanes from racemic
