A direct conversion of alcohols into nitriles with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO), iodosobenzene diacetate, and ammonium acetate as a nitrogen source is reported. This transformation, which proceeds through an oxidation–imination–aldimine oxidation sequence in situ, has been applied to a range of aliphatic, benzylic, heteroaromatic, allylic, and propargyl alcohols. Highly chemoselective
据报道,使用 2,2,6,6-四甲基哌啶-1-氧基 (TEMPO)、二乙酸碘苯和乙酸铵作为氮源,将醇直接转化为腈。这种通过原位氧化-亚胺化-醛亚胺氧化序列进行的转化已应用于一系列脂肪醇、苄醇、杂芳醇、烯丙醇和炔丙醇。还实现了在仲醇存在下伯醇的高度化学选择性氨氧化。
