Photocatalytic EnT-Mediated Aminophosphorylation of Alkenes Using Oxime Esters as Bifunctional Reagents.

C-P bond formation has typically been achieved by a single-electron transfer process. Herein, a novel class of oxime ester bifunctionalization reagents were first applied to the photocatalytic β-aminophosphorylation of modular olefins. The bifunctional reagents generate two distinct radical species (imine and phosphoryl radicals) that exhibit excellent regioselectivity.

Triazine-Carbazole-Based Covalent Organic Frameworks as Efficient Heterogeneous Photocatalysts for the Oxidation of N-aryltetrahydroisoquinolines.

Covalent organic frameworks (COFs) have attracted growing interests as new material platform for a range of applications. In this study, a triazine-carbazole-based covalent organic framework (COF-TCZ) was designed as highly porous material with conjugated donor-acceptor networks, and feasibly synthesized by the Schiff condensation of 4,4',4''-(1,3,5-triazine-2,4,6-triyl)tr ianiline (TAPB) and 9-(4-formylphenyl)-9H-carbazole-3,6-dicarbaldehyde (CZTA) under the solvothermal condition. Considering the effect of linkage, the imine-linked COF-TCZ was further oxidized to obtain an amide-linked covalent organic framework (COF-TCZ-O).
