Electronic tuning: Nitroxyl radical 1 is shown to be an efficient catalyst for the oxidation of secondary alcohols, and promotes oxidation through an oxoammonium species which is highly reactive because of the adjacent electron‐withdrawing ester groups. Chemoselective oxidation of benzylic alcohols in the presence of aliphatic alcohols is observed and is proposed to proceed by a rate‐determining hydride
电子调谐:硝基1自由基是仲醇氧化的有效催化剂,并通过氧铵盐类促进氧化,该氧铵盐类由于相邻的吸电子酯基团而具有很高的反应性。可以观察到在脂肪族醇存在下苄醇的化学选择性氧化,并建议通过决定氢化物转移的速率进行。
