highly efficient and selective oxidation of primary and tertiary amines employing SO2F2/H2O2/base system was described. Anilines were converted to the corresponding azoxybenzenes, while primary benzylamines were transformed into nitriles and secondary benzylamines were rearranged to amides. For tertiary amine substrates quinolines, isoquinolines and pyridines, their oxidation products were the corresponding
描述了使用 SO 2 F 2 /H 2 O 2 /碱系统对伯胺和叔胺进行高效和选择性氧化。苯胺转化为相应的偶氮苯,而伯苄胺转化为腈,仲苄胺重排为酰胺。对于叔胺底物喹啉、异喹啉和吡啶,它们的氧化产物是相应的N-氧化物。反应条件非常温和,仅涉及 SO 2 F 2、胺类、30% H 2 O 2水溶液溶液和无机碱在室温下。一个独特的优点是该氧化系统仅由廉价的无机化合物组成,而没有使用任何金属和有机化合物。
