A fluorinated phosphite traps alkoxy radicals photogenerated at the air/solid interface of a nanoparticle

With interests in alkoxy radical formation on natural and artificial surfaces, a physical-organic study was carried out with a Hammett series of triaryl phosphites (p-MeO, H, p-F, and p-Cl) to trap adsorbed alkoxy radicals on silica nanoparticles. A mecha

Method for preparing phosphate ester derivatives from white phosphorus

A method for preparing phosphate ester derivatives from white phosphorus relates to the field of chemical engineering, and comprises the following steps: adding alkali, a catalyst, a white phosphorus solution, ROH or RSH (R represents alkyl or aromatic group) into a reaction container in an inert atmosphere, and heating and stirring the mixture in a mixed solvent of toluene and DMSO (dimethyl sulfoxide) to react for a certain time, so as to obtain three-coordinated phosphate ester derivatives; and 2) continuing to add H2O2, air or sulfur powder until the oxidation is completed, thereby obtaining the tetra-coordinated phosphate ester derivative. According to the method, chlorine, phosphorus trichloride and halogen are not needed, phosphite ester is directly prepared from elementary white phosphorus in an efficient, green and environment-friendly manner, and phosphate and thiophosphate can be directly prepared after oxidation. High pollution and high corrosivity of a traditional method are avoided in the whole process; meanwhile, white phosphorus is completely converted in the whole process, white phosphorus residues are avoided, and the post-reaction treatment process is safe.

Flash production of organophosphorus compounds in flow

Flow synthesis techniques have received a significant amount of attention due to their high productivity. However, when reaction condition is heterogeneous, it is usually difficult to adapt it to flow synthesis. Herein, by selecting appropriate reagents, the synthesis of phosphate esters, which is commonly heterogeneous, was made homogeneous, enabling synthesis in flow systems. In addition, reaction rate was accelerated compared to the batch system. It was demonstrated that not only can the high productivity of flow synthesis be achieved in flow, but also high productivity can be achieved by accelerating the reaction. Finally, we demonstrated the synthesis of the Akiyama-Terada catalyst, a chiral organocatalysts, in a short period.
