Korsager, Signe; Taaning, Rolf H.; Skrydstrup, Troels published the article 《Effective Palladium-Catalyzed Hydroxycarbonylation of Aryl Halides with Substoichiometric Carbon Monoxide》. Keywords: palladium catalyst hydroxycarbonylation aryl halide substoichiometric carbon monoxide; aromatic carboxylic acid preparation.They researched the compound: 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine( cas:52287-51-1 ).Formula: C8H7BrO2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:52287-51-1) here.
A protocol for the Pd-catalyzed hydroxycarbonylation of aryl iodides, bromides, and chlorides has been developed using only 1-5 mol % of CO, corresponding to a pCO as low as 0.1 bar. Potassium formate is the only stoichiometric reagent, acting as a mildly basic nucleophile and a reservoir of CO. The substoichiometric CO could be delivered to the reaction from an acyl-Pd(II) precatalyst, which provides both the CO and an active catalyst, and thereby obviates the need for handling a toxic gas.
