I found the field of Chemistry very interesting. Saw the article Highly Efficient N-Heterocyclic Carbene/Ruthenium Catalytic Systems for the Acceptorless Dehydrogenation of Alcohols to Carboxylic Acids: Effects of Ancillary and Additional Ligands published in 2020. Application In Synthesis of 3-Methylbenzoic acid, Reprint Addresses Chen, C; Verpoort, F (corresponding author), Wuhan Univ Technol, State Key Lab Adv Technol Mat Synth & Proc, 122 Luoshi Rd, Wuhan 430070, Peoples R China.; Verpoort, F (corresponding author), Natl Res Tomsk Polytech Univ, Lenin Ave 30, Tomsk 634050, Russia.; Verpoort, F (corresponding author), Ghent Univ Global Campus, Ctr Environm & Energy Res, 119 Songdomunhwa Ro, Incheon 406840, South Korea.. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid
The transition-metal-catalyzed alcohol dehydrogenation to carboxylic acids has been identified as an atom-economical and attractive process. Among various catalytic systems, Ru-based systems have been the most accessed and investigated ones. With our growing interest in the discovery of new Ru catalysts comprising N-heterocyclic carbene (NHC) ligands for the dehydrogenative reactions of alcohols, we designed and prepared five NHC/Ru complexes ([Ru]-1-[Ru]-5) bearing different ancillary NHC ligands. Moreover, the effects of ancillary and additional ligands on the alcohol dehydrogenation with KOH were thoroughly explored, followed by the screening of other parameters. Accordingly, a highly active catalytic system, which is composed of [Ru]-5 combined with an additional NHC precursor L5, was discovered, affording a variety of acid products in a highly efficient manner. Gratifyingly, an extremely low Ru loading (125 ppm) and the maximum TOF value until now (4800) were obtained.
