heterogeneous photocatalyst, NPh3 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[d]imidazo[1,5-b]isothiazole 5,5-dioxides can be efficiently synthesized through the visible-light-induced cascade decarboxylative coupling/annulation reaction.
首次报道了 SrTiO3 半导体在有机合成中用作光催化剂,并在光催化中使用 NPh3 作为氧化还原催化剂。以 SrTiO3 为非均相光催化剂,NPh3 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,通过可见光诱导的级联脱羧偶联/环化反应,可以高效合成各种 1,2,3,9b-四氢苯并[d]咪唑[1,5-b]异噻唑 5,5-二氧化物。
