Application of 538-58-9, Chemical Research Letters, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic. In a document type is Article, and a compound is mentioned, 538-58-9, Name is 1,5-Diphenylpenta-1,4-dien-3-one, introducing its new discovery.
The first example of a regioselective beta-arylation of benzo[b]thiophenes and thiophenes at room temperature with aryl iodides as coupling partners is reported. This methodology stands out for its operational simplicity: no prefunctionalization of either starting material is required, the reaction is insensitive to air and moisture, and it proceeds at room temperature. The mild conditions afford wide functional group tolerance, often with complete regioselectivity and high yields, resulting in a highly efficient catalytic system. Initial mechanistic studies, including 13C and 2H KIEs, suggest that this process occurs via a concerted carbo-palladation across the thiophene double bond, followed by a base-assisted anti-elimination.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about538-58-9.Application of 538-58-9
