The first applying SrTiO semiconductor as a photocatalyst in organic synthesis and using NPh as a redox catalyst in photocatalysis was reported. With SrTiO as the heterogeneous photocatalyst, NPh as the homogeneous redox catalyst, H-bond as the promoter, paraformaldehyde as the cheap and atom economic methylene source, various 1,2,3,9b-tetrahydrobenzo[]imidazo[1,5-]isothiazole 5,5-dioxides can be efficiently synthesized through the visible-light-induced cascade decarboxylative coupling/annulation reaction.

H键促进NPh3介导的SrTiO3光催化级联脱羧偶联/苯并[d]异噻唑1,1-二氧化物成环


首次报道了SrTiO半导体作为有机合成光催化剂和NPh作为光催化氧化还原催化剂。以SrTiO为多相光催化剂，NPh为均相氧化还原催化剂，H键为促进剂，多聚甲醛为廉价且原子经济的亚甲基源，各种1,2,3,9b-四氢苯并[]咪唑并[1,5-]异噻唑 5,5-二氧化物可以通过可见光诱导的级联脱羧偶联/成环反应有效合成。
