The H5PV2Mo10O40 polyoxometalate catalysed the electron transfer oxidation of sulphite to yield a sulphite radical, SO3 (-) that upon addition of O2 yielded a peroxosulphate species efficient for the H5PV2Mo10O40 catalysed epoxidation of alkenes. The acidic polyoxometalate further catalysed hydrolysis of the epoxide to give vicinal diols in high yields.
H5PV2Mo10O40多金属氧酸盐催化亚硫酸盐的电子转移氧化,生成亚硫酸根自由基SO3(-),在添加O2后产生对H5PV2Mo10O40催化的烯烃环氧化有效的过氧硫酸盐类。酸性多金属氧酸盐进一步催化环氧化物的水解,以高收率得到邻位二醇。
