Arylazo sulfones were used as Photoacid Generators (PAGs) for the visible-light photorelease of strong sulfonic acids to promote the ring opening of epoxides in benign media (DMC/water mixtures) or under neat conditions. Water, alcohols, azide and thiocyanate anions, as well as electron-rich aromatics were used in the role of the nucleophile. The resulting 1,2-disubstituted adducts were formed mostly
芳基偶氮砜被用作光产酸剂 (PAG),用于强磺酸的可见光光释放,以促进良性介质(DMC/水混合物)或纯净条件下环氧化物的开环。水、醇、叠氮化物和硫氰酸根阴离子以及富电子芳香族化合物被用作亲核试剂。所得 1,2-二取代加合物以高区域选择性方式形成,产率大部分为 >99%。
