I found the field of Chemistry very interesting. Saw the article Rhenium-Catalyzed Reduction of Carboxylic Acids with Hydrosilanes published in 2019. Product Details of 90-27-7, Reprint Addresses Sortais, JB (corresponding author), Univ Toulouse, UPS, CNRS, LCC, Toulouse, France.; Sortais, JB (corresponding author), Inst Univ France, 1 Rue Descartes, F-75231 Paris 05, France.. The CAS is 90-27-7. Through research, I have a further understanding and discovery of 2-Phenylbutanoic acid
Re-2(CO)(10) efficiently catalyzes the direct reduction of various carboxylic acids under mild conditions (rt, irradiation 350 or 395 nm). While aliphatic carboxylic acids were readily converted to the corresponding disilylacetals with low catalyst loading (0.5 mol %) in the presence of Et3SiH (2.2 equiv), aromatic analogues required more drastic conditions (Re-2(CO)(10) 5 mol %, Ph2MeSiH 4.0 equiv) to afford the corresponding aldehydes after acid treatment.
About 2-Phenylbutanoic acid, If you have any questions, you can contact Wei, D; Buhaibeh, R; Canac, Y; Sortais, JB or concate me.. Product Details of 90-27-7
