In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C9H6O3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 496-41-3, name is Benzofuran-2-carboxylic acid. In an article£¬Which mentioned a new discovery about 496-41-3
Oxidative Cleavage of beta -Keto Sulfones via Nitrous Acid
The reaction of nitrous acid with 1-aryl-2-(arylsulfonyl)ethanones 3a-e afforded the unexpected arenecarboxylic acids 12a-e, formic acid 14, and benzene/4-toluenesulfinic acid 15a, b through oxidative cleavage reaction. 4-Chlorobenzoic acid (12a), [1,1?-biphenyl]-4-carboxylic acid (12b), 2-naphthoic acid (12c), 2-thiophenecarboxylic acid (12d), and 2-benzofurancarboxylic acid (12e) were isolated in 72%, 62%, 55%, 58%, and 62% yields, respectively. The reported mechanistic pathways proposed the production of 1-aryl-2-(phenyl/tolylsulfonyl)ethane-1,2-dione 7 instead of arenecarboxylic acids 12. A mechanistic pathway to explain the reaction of nitrous acid with 1-aryl-2-(arylsulfonyl)ethanones 3a-e was suggested. In this pathway, the intermediate 1,2-oxazete 10 lost benzene/4-toluenesulfinic acid 15 to produce 1,2-oxazet-3-one 11. Ring cleavage of the latter intermediate afforded the arenecarboxylic acids 12.
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 496-41-3, help many people in the next few years.HPLC of Formula: C9H6O3
