oxygenation of nonactivated aliphatic C(sp3)–H groups with peroxycarboxylic acids in the presence of palladium tris(pyridylmethyl)amine complex (0.6 mol %) is reported, providing the corresponding hydroxylated derivatives in up to 94% yields. The oxidation of 3° C–H groups occurs stereospecifically, with the catalyst system demonstrating extremely high sensitivity to electronic effects (adamantane oxidation:
据报道,在钯三(吡啶基甲基)胺络合物(0.6 mol%)的存在下,未活化的脂肪族 C(sp 3 )–H 基团与过氧羧酸直接氧化,以高达 94% 的收率提供相应的羟基化衍生物。3° C–H 基团的氧化立体有择地发生,催化剂系统对电子效应表现出极高的敏感性(金刚烷氧化:3°:2° 高达 >300)。这表明天然来源的复杂分子的 3°-区域选择性氧化功能化的潜在应用。
