K2S2O8-Promoted Direct C–H Phosphorylation of (Benzo)thiazoles

The direct phosphorylation of (benzo)thiazoles with various H-phosphine oxides was realized by using K2S2O8 as the oxidant. A series of 2-phosphoryl (benzo)thiazoles were obtained in moderate to good yields.

Visible-Light-Induced Metal-Free Synthesis of 2-Phosphorylated Thioflavones in Water

The introduction of phosphorus functional groups into the skeleton of thioflavones is an attractive task and of great significance. Herein, a metal-free visible-light-induced radical cascade cyclization was developed for the preparation of 2-phosphorylate

Silver-mediated direct phosphorylation of benzothiazoles and thiazoles with diarylphosphine oxides

A silver nitrate-mediated, efficient phosphorylation of benzothiazoles and thiazoles with diarylphosphine oxides was developed. This process provides a convenient route for the synthesis of a variety of 2-diarylphosphoryl benzothiazoles and thiazoles which are promising precursors of a series of hemilabile P,N-ligands with small bite angles.

Cross-coupling hydrogen evolution by visible light photocatalysis toward C(sp2)-P formation: Metal-free C-H functionalization of thiazole derivatives with diarylphosphine oxides

Visible light along with 5 mol % eosin B catalyzed the first direct C-H phosphorylation of thiazole derivatives with diarylphosphine oxides by a photoredox process in the absence of an external oxidant. The scope of thiazoles and phosphine oxides was further investigated, as was functional group tolerance. The general and operational simplicity provides a novel metal and oxidant-free alternative for the formation of heteroaryl-P bonds, and only molecular hydrogen is generated as a byproduct.

Electrochemical Oxidative C–H Phosphonylation of thiazole derivatives in ambient conditions

We herein report a direct electrochemical dehydrogenative C–H phosphonylation of thiazoles derivatives with H2 evolution. Employing electricity as the green and sole oxidant, cheap metal as electrode, the anodic oxidation together with cathodic hydrogen evolution process provides a green and efficient strategy for C–H phosphonylation. A diverse range of phosphorus products were constructed under external metal and oxidant-free conditions at ambient temperature, featuring atom economy, simple operation and wide reaction scope.

4CzIPN-tBu-Catalyzed Proton-Coupled Electron Transfer for Photosynthesis of Phosphorylated N-Heteroaromatics

2,4,5,6-Tetrakis(3,6-di-tert-butyl-9H-carbazol-9-yl)isophthalonitrile (4CzIPN-tBu) was developed as a photocatalyst for the phosphorus-radical-initiated cascade cyclization reaction of isocyanides. By using 4CzIPN-tBu as catalyst, we developed a visible-light-induced proton-coupled electron transfer strategy for the generation of phosphorus-centered radicals, via which a wide range of phosphorylated phenanthridines, quinolines, and benzothiazoles were successfully constructed.

Embedding CsPbBr3quantum dots into a pillar[5]arene-based supramolecular self-assembly for an efficient photocatalytic cross-coupling hydrogen evolution reaction

Light-harvesting is a key step in photosynthesis, but it is still a challenge to create an efficient artificial light harvesting system in a broader solar spectrum to mimic natural processes. Here, we have fabricated, for the first time, a highly efficient artificial light-harvesting system through directly embedding CsPbBr3quantum dots (QDs) inside a supramolecular self-assembly of thymine functionalized-pillar[5]arene (PTY) and an eosin Y-based derivative (EYB). The donor CsPbBr3QDs exhibit a broad spectral absorption in the UV-visible range, and their emission shows good spectral overlap with the absorption of EYB, thus effective excitation energy is transferred from CsPbBr3to the acceptor EYB with an energy transfer efficiency of 96.5%. Importantly, the combination displayed excellent photocatalytic activity in cross-coupling hydrogen evolution reactions, and the product yield was more than 2.5 times that obtained using eosin Y alone. Our research opens up a new avenue for utilizing perovskite QDs with broad spectral absorption as the energy donor to construct efficient light-harvesting systems for solar energy conversion.

Metal-free photo-induced radical C-P and C-S bond formation for the synthesis of 2-phosphoryl benzothiazoles

We reveal here a visible-light promoted phosphorylation of 2-isocyanoaryl thioethers for the first time with concomitant C(sp3)-S bond cleavage and imidoyl C–S formation. Additionally, this method features the use of 3 mol% organic dye Rose Bengal as the photocatalyst without external transition-metal or peroxide oxidants, and provides a novel and environmentally friendly approach for the preparation of a variety of 2-phosphoryl benzothiazoles in moderate to good yields.

Visible-light-induced ligand-free RuCl3 catalyzed C-H phosphorylation in water

Visible-light-induced C-H phosphorylation of para-CAr-H and heteroarenes was realized using cost-effective RuCl3 as a catalyst. The reaction conditions are green and environmentally friendly, using water as a solvent at room temperature and without ligands. A broad range of highly functional organophosphorus compounds were obtained via a cross-dehydrogenation-coupling (CDC) reaction. In addition, we also proved that RuCl3 is a photocatalyst via its absorption spectrum and on/off light experiments.

Aqueous Platinum(II)-Cage-Based Light-Harvesting System for Photocatalytic Cross-Coupling Hydrogen Evolution Reaction

Photosynthesis is a process wherein the chromophores in plants and bacteria absorb light and convert it into chemical energy. To mimic this process, an emissive poly(ethylene glycol)-decorated tetragonal prismatic platinum(II) cage was prepared and used a
