synthetically attractive perfluoroalkyl ketones through the reaction of readily available alkenoates, alkynoates, or regular carboxylic esters with perfluoroalkyl Grignardreagents at -70 to -60 °C in diethyl ether with moderate to good yields was developed. The reaction stopped at the ketone stage, with no further reaction to form the tertiary alcohols being observed. DFT calculations confirmed that
开发了一种通过容易获得的烯酸酯、炔酸酯或常规羧酸酯与全氟烷基格氏试剂在 -70 至 -60 °C 下在二乙醚中反应以中等至良好产率制备具有合成吸引力的全氟烷基酮的有效方法。反应在酮阶段停止,没有观察到进一步反应形成叔醇。DFT 计算证实,与普通酮相比,全氟烷基取代的酮的亲电性较低。
