H2O (1) containing a dinuclear iron(III) complex in which HPTB=N,N,N′,N′-tetrakis(2-benzimidazolylmethyl)-2-hydroxo-1,3-diaminopropane catalyzes the oxidation of alkanes with hydrogen peroxide in acetonitrile solution at room temperature only if certain amino acids (pyrazine-2-carboxylic, pyrazine-2,3-dicarboxylic or picolinic acid) are added to the reaction mixture. Alkyl hydroperoxides are formed
化合物[Fe 2(HPTB)(μ-OH)(NO 3)2 ](NO 3)2 ·CH 3 OH·2H 2 O(1)含有双核铁(III)配合物,其中HPTB = N,N,N ',N仅在某些氨基酸(吡嗪-2-羧酸,吡嗪-2,3-)在室温下,'-四(2-苯并咪唑基甲基)-2-羟基-1,3-二氨基丙烷催化过氧化氢在乙腈溶液中氧化烷烃。将二羧酸或吡啶甲酸加入到反应混合物中。烷基氢过氧化物形成为主要反应产物。环己烷的周转率达到140,乙烷的周转率达到21,甲烷氧化的周转率达到4。氧化非立体选择性地进行,并且键选择性参数低,这证明了羟基自由基参与烷烃官能化。
