Ag (I) mediated persulphate oxidation of various 2-methyl benzoic acids and acrylic acids, co-catalyzed by Cu (II), leads to unsaturated γ-lactones, together with decarboxylation products. Lactonisation proceeds through 1,5 hydrogen transfer from intermediate acyloxyl radicals.
由铜(II)共同催化的银(I)介导的各种2-甲基苯甲酸和丙烯酸的过硫酸盐氧化,会导致不饱和γ-内酯以及脱羧产物。漆酸化是通过从中间酰氧基自由基进行的1.5氢转移而进行的。
