  Arylative Desulfonation of Diarylmethyl Phenyl Sulfone with Arenes Catalyzed by Scandium Triflate

  摘要：

  A scandium-triflate-catalyzed arylative desulfonation of diarylmethyl phenyl sulfones with arenes and heteroarenes was established. A variety of both sulfone and arene substrates were reacted to afford symmetric and nonsymmetric triarylmethanes in good yields. Further transformations of the resulting triarylmethanes and application to the concise synthesis of a bactericidal agent analogue were also demonstrated.

  Simple and efficient procedure for alkylation of aromatics from alcohols in the presence of NaHSO4/SiO2 was developed. Various triaryl methanes were obtained in good yields in short reaction time. For instance the reaction of mesitylene with benzhydrol in the presence of NaHSO4/SiO2 gave the corresponding triaryl methane in a quantitative yield. NaHSO4/SiO2 was regenerated by simple treatment and could

  在NaHSO 4 / SiO 2的存在下，开发了一种简单有效的从醇类将芳烃烷基化的方法。在短的反应时间内以高收率获得了各种三芳基甲烷。例如，在NaHSO 4 / SiO 2的存在下，1，3，5-三甲基苯与苯甲醇的反应以定量收率得到了相应的三芳基甲烷。NaHSO 4 / SiO 2通过简单处理即可再生，可以循环使用八次而不会损失活性。

  Simple and efficient methods were developed for sp(2)-sp(3) and sp(3)-sp(3) C-C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported Bronsted acid containing sulfonic groups. The carbocation formed by cleavage of the sp(3)-sp(3) C-C bond of the dione alkylated the aromatic compound.
