Photodriven oxidations of alkanes in trifluoroacetic acid using commercial and synthesized Fe(III) sources as catalyst precursors and dioxygen (O2) as the terminal oxidant are reported. The reactions produce alkyl esters and occur at ambient temperature in the presence of air, and catalytic turnover is observed for the oxidation of methane in a pure O2 atmosphere. Under optimized conditions, approximately
报道了使用商业和合成的 Fe(III) 源作为催化剂前体和分子氧 (O 2 ) 作为末端氧化剂的三氟乙酸中烷烃的光驱动氧化。该反应产生烷基酯并在空气存在下在环境温度下发生,并且在纯 O 2气氛中观察到甲烷氧化的催化转化。在优化条件下,观察到大约 17% 的甲烷转化为三氟乙酸甲酯,选择性超过 50%。证明三氟乙酸甲酯在催化条件下是稳定的,因此不会通过三氟乙酸甲酯的二次氧化形成过氧化产物。
