• An efficient method for aromatic Friedel–Crafts alkylation, acylation, benzoylation, and sulfonylation reactions

  Aromatic electrophilic substitution reactions such as alkylation, acylation, benzoylation, and sulfonylation were studied in the presence of a catalytic amount of Cu(OTf)2 and Sn(OTf)2. Cu(OTf)2 was very efficient for alkylation, acylation, and benzoylation reactions. However, in case of sulfonylation reactions, Sn(OTf)2 gave better results.

  在催化量的Cu（OTf）2和Sn（OTf）2存在下，研究了烷基化，酰化，苯甲酰化和磺酰化等芳香亲电取代反应。Cu（OTf）2对于烷基化，酰化和苯甲酰化反应非常有效。然而，在磺酰化反应的情况下，Sn（OTf）2给出了更好的结果。

  reactive and/or nonvolatile reagents (anisole, xylenes, mesitylene) expeditious conditions (short reaction time at constant MW power without control of the temperature) were used. With less reactive and/or low-boiling reagents (benzene, toluene, halobenzenes), the rise in temperature and the increase of reaction time were controlled either by sequential MW irradiation or by a temperature order. It was shown

  苯及其活化或失活衍生物的无溶剂磺酰化反应是在微波（MW）辐射和催化量的氯化铁（III）的条件下进行的，在这些条件下，氯化铁（III）的活性高于其他金属盐。对于反应性和/或非挥发性试剂（苯甲醚，二甲苯，均三甲苯）使用较快的条件（在恒定MW功率下，反应时间短而不控制温度）。对于反应性较低和/或沸点较低的试剂（苯，甲苯，卤代苯），可通过顺序进行MW辐射或按温度顺序控制温度的升高和反应时间的增加。结果表明，MWs与反应中存在的极性物质（尤其是芳基砜及其FeCl3络合形式）发生优先相互作用。

  Silica gel-supported aluminum chloride (SiO2–AlCl3) has been shown to be a mild, efficient, and chemoselective heterogeneous Lewis acid catalyst for direct conversion of arenes to sulfones using sulfonic acids as sulfonylating agents. The catalyst can be prepared easily with cheap starting materials and is stable (as a bench-top catalyst) and reusable.

  supported aluminium triflate (Ps-Al(OTf)3) was found to be an efficient and chemoselective heterogeneous Lewis acid catalyst for the direct conversion of arenes to sulfones using sulfonic acids as sulfonylating agents. The solid acid catalyst is stable (as a bench top catalyst) and can be easily recovered and reused without appreciable change in its efficiency.
