摘　　要：许多稳定的无机阴离子经过氧化都能得到相应的高活性的自由基,该转化中可见光可激发的光催化剂可以提供所需的氧化势能,空气中的氧气和一些常见的氧化剂均可用作终端氧化剂。综述了NO_3^-、SCN^-、N_3^-和亚磺酸根这几种无机阴离子通过1e^-氧化生成自由基中间体的过程机理及其应用,此外,介绍了"Cl^-"经过2e^-氧化制备亲电氯离子的过程,最后对光催化氧化阴离子制备自由基在有机合成中的应用进行了展望。Radicals with high reactivity can be obtained by the oxidation of stable inorganic anions,during which the required oxidation potential can be provided by visible light exciting photocatalyst and both oxygen and common oxidants can be used as terminal oxidants.The mechanisms and applications of inorganic anions（NO3^-,SCN^-,N3^-,and sulfinates）for the transformation to radical intermediates by one-electron oxidation are reviewed.Furthermore,the process of generating electrophilic chlorine through two-electron oxidation of chloride anions is summarized.Finally,we also offer the insight into future research trends and developments including potential applications in organic synthesis for radicals prepared by photo-catalytic oxidation anions.
