The copper(I)-catalyzed oxidation of alkenes with molecular oxygen and N-hydroxyphthalimide (NHPI) or N-hydroxybenzotriazole (HOBt) provided α-oxygenated ketones. The reaction proceeded under a balloon of O2 at room temperature to furnish the dioxygenated products in 50–90% yield. These compounds, particularly the HOBt derivatives, can be further functionalized with phosphorus, nitrogen, and sulfur
铜(I)催化的烯烃与分子氧和N-羟基邻苯二甲酰亚胺(NHPI)或N-羟基苯并三唑(HOBt)的氧化提供了α-氧化的酮。反应在室温下在O 2气球下进行,以50-90%的收率提供双氧合产物。这些化合物,特别是HOBt衍生物,可以用磷,氮和硫亲核试剂进一步官能化,以提供合成上有用的产物。
