A cheap, mild and environmentally friendly oxidation of tertiary amines and azines to the corresponding N‐oxides is reported by using polyfluoroalkyl ketones as efficient organocatalysts. 2,2,2‐Trifluoroacetophenone was identified as the optimum catalyst for the oxidation of aliphatic tertiary amines and azines. This oxidation is chemoselective and proceeds in high‐to‐quantitative yields utilizing
通过使用多氟烷基酮作为有效的有机催化剂,可以廉价,温和且环保地将叔胺和嗪氧化为相应的N-氧化物。2,2,2-三氟苯乙酮被确定为脂族叔胺和嗪氧化的最佳催化剂。这种氧化具有化学选择性,并利用10 mol%的催化剂和H 2 O 2作为氧化剂,以高至定量的产率进行。
