A new protocol for the oxidative coupling of ketone oximes with dialkyl/diarylphosphine oxides to synthesize O-(dialkylphosphinyl)ketone oximes has been developed. Hydrogen peroxide is used as a green oxidizing agent, and molecular iodine is used as a nonmetal catalyst. The reaction has a high atom economy, with water as the only byproduct. O-(Dialkylphosphinyl)ketone oximes with 26 examples have been obtained with high yields. Furthermore, the product may be transformed into other molecules, i.e., by reduction.

酮肟和二烷基/二芳基膦氧化物的 I2 催化氧化偶联

已经开发了一种用于将酮肟与二烷基/二芳基氧化膦氧化偶联以合成 O-(二烷基膦基) 酮肟的新协议。过氧化氢用作绿色氧化剂，分子碘用作非金属催化剂。该反应具有高原子经济性，水是唯一的副产品。O-(二烷基膦基)酮肟以高收率获得了26个实例。此外，产物可以转化为其他分子，即通过还原。
