A photoredox activation mode of formate salts for carboxylation was developed. Using a formate salt as the reductant, carbonyl source, and hydrogen atom transfer reagent, a wide range of alkenes can be converted into acid products via a carboxyl group tra

Paragraph 0047-0054, (2021/04/21)
The invention discloses a method for synthesizing phenylpropionic acid compounds by heterogeneous catalysis. The method comprises the following steps: sequentially adding Pd@POL, toluene, styrene, formic acid and acetic anhydride into a reaction flask, stirring the reaction mixture at 80 DEG C to react, cooling the reaction solution to room temperature after the reaction is finished, diluting with dichloromethane, and transferring the solution into a separating funnel, washing with a sodium hydroxide solution, acidifying the water layer with a hydrochloric acid aqueous solution, extracting with dichloromethane, merging organic phases, drying with anhydrous sodium sulfate, and carrying out vacuum concentration to obtain the phenylpropionic acid compound. The method can remove heavy metal residues, is green and environment-friendly, is simple to operate and easy to implement, and the prepared phenylpropionic acid compound has a good application prospect.

A range of hitherto unexplored biomass-derived chemicals have been evaluated as new sustainable solvents for a large variety of CO2-based carboxylation reactions. Known biomass-derived solvents (biosolvents) are also included in the study and the results are compared with commonly used solvents for the reactions. Biosolvents can be efficiently applied in a variety of carboxylation reactions, such as Cu-catalyzed carboxylation of organoboranes and organoboronates, metal-catalyzed hydrocarboxylation, borocarboxylation, and other related reactions. For many of these reactions, the use of biosolvents provides comparable or better yields than the commonly used solvents. The best biosolvents identified are the so far unexplored candidates isosorbide dimethyl ether, acetaldehyde diethyl acetal, rose oxide, and eucalyptol, alongside the known biosolvent 2-methyltetrahydrofuran. This strategy was used for the synthesis of the commercial drugs Fenoprofen and Flurbiprofen.
