In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 3-Methylbenzofuran-2-carboxylic acid, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 24673-56-1, name is 3-Methylbenzofuran-2-carboxylic acid. In an article，Which mentioned a new discovery about 24673-56-1
By using Pd(TFA)2/PCy3 as a catalyst, a broad range of aromatic carboxylic acids, including heteroaromatic carboxylic acids, efficiently underwent decarboxylative coupling with an array of polyfluoroarenes in the presence of stoichiometric amount of silver salts to generate biaryls. Silver salts were adjusted to the reactivity of aromatic carboxylic acids to efficiently suppress the protodecarboxylation and therefore improve decarboxylative cross-couplings. It was established that the palladium complex containing the PCy3 ligand was capable of catalyzing the decarboxylation of electron-rich aromatic carboxylic acids, and silver salts promoted the decarboxylation of both electron-rich and -deficient ones. To explain the two different decarboxylation processes, two possible reaction pathways are proposed, which were further supported by the facts that the stoichiometric arylpalladium complex can directly arylate pentafluorobenzene in the presence of PCy3 and the arylpalladium complex can catalyze the decarboxylative coupling of 2,4-dimethoxybenzoic acid with pentafluorobenzene. The kinetic isotope effect of 4.0 clearly showed that theC-H bond cleavage of polyfluoroarenes is involved in the rate-determining step.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 24673-56-1, help many people in the next few years.Safety of 3-Methylbenzofuran-2-carboxylic acid
