Perovskite as Recyclable Photocatalyst for Annulation Reaction of N-Sulfonyl Ketimines

Organic Letters, Год журнала: 2021, Номер 24(1), С. 299 - 303

Опубликована: Дек. 16, 2021

A sustainable and cost-effective manner for the photocatalytic annulation reaction of N-sulfonyl ketimines with N-arylglycines to synthesize imidazolidine-fused sulfamidates (31 examples) by employing CsPbBr3 as a heterogeneous photocatalyst has been developed. The catalyst can be simply recovered from mixture reused at least five times without an obvious reduction in its reactivity, exhibiting high economic feature.
