Sodium selenite catalyses, under mild conditions, the reductive debromination of vic-dibromides [e.g., meso- or (±)-1,2-dibromo-1,2-diphenylethane, trans-10,11-dibromodibenzosuberone, 2,3-dibromo-1,3-Biphenyl-1-propanone, α,β-dibromobenzenepropanoic acid, and cholesterol dibromide] to alkenes in the presence of the thiols cysteine or glutathione.
亚硒酸钠催化作用,在温和条件下,的还原脱溴VIC -dibromides [例如,内消旋-或(±)-1,2-二溴-1,2-二苯基乙烷,反式-10,11- dibromodibenzosuberone,2,3-二溴-1,3-联苯-1-丙酮,α,β-二溴苯丙酸和胆固醇二溴化物]在硫醇半胱氨酸或谷胱甘肽的存在下转化为烯烃。
