(λ=210 nm) promoted procedure proceeding in aqueous media at room temperature using ambient air as the oxidant for efficient synthesis of an array of α‐ketoamides of all types using a non‐metal catalyst N‐iodosuccinimide with a loading of 20 mol%. With UV, oxygen in the air was efficiently utilized as the green oxidant, some control experiments were carried out and a plausible mechanism was proposed

Presented here is the first example of synthesizing an array of primary-, secondary-, and tertiary-α-ketoamides with a non-metal catalyst nBu4NI from methylketones and inexpensive readily available amine/ammonium salts; the reactions proceeded smoothly under mild conditions, TBHP was used as an oxidant and the corresponding α-ketoamides were afforded in moderate to excellent yields.
这是从甲基酮和廉价的容易得到的胺/铵盐合成带有非金属催化剂n Bu 4 NI的一系列伯,仲和叔α-酮酰胺的第一个例子。在温和的条件下,反应平稳进行,使用TBHP作为氧化剂,并以中等至极好的收率提供了相应的α-酮酰胺。
