In 2019,Chemical Science included an article by Liu, Chengwei; Qin, Zhi-Xin; Ji, Chong-Lei; Hong, Xin; Szostak, Michal. Computed Properties of C9H8O4. The article was titled 《Highly-chemoselective step-down reduction of carboxylic acids to aromatic hydrocarbons via palladium catalysis》. The information in the text is summarized as follows:
The highly selective method for the direct step-down reduction of carboxylic acids RCOOH (biphenyl-4-yl, 1-naphthyl, 1-methyl-1H-indole-3-yl, etc.) to arenes RH, proceeding via well-defined Pd(0)/(II) catalytic cycle was described. The method shows a remarkably broad substrate scope, enabling to direct the classical acyl reduction towards selective decarbonylation by a redox-neutral mechanism. The utility of this reaction is highlighted in the direct defunctionalization of pharmaceuticals and natural products, and further emphasized in a range of traceless processes using removable carboxylic acids under mild, redox-neutral conditions orthogonal to protodecarboxylation. Extensive DFT computations were conducted to demonstrate preferred selectivity for the reversible oxidative addition and indicated that a versatile hydrogen atom transfer (HAT) pathway is operable. The experimental part of the paper was very detailed, including the reaction process of 3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0Computed Properties of C9H8O4)
3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market.Computed Properties of C9H8O4
