Reversible energy transfer and oxetane formation in the photoreactions of carbonyl compounds with benzofurans was written by Farid, S.;Hartman, S. E.;DeBoer, C. D.. And the article was included in Journal of the American Chemical Society in 1975.COA of Formula: C10H8O3 This article mentions the following:
The photoreactions of propiophenone and acetophenone with benzofuran lead both to dimerization of the olefin and to oxetane formation. The dependency of the product ratio on the concentration of the reactants can be rationalized in terms of 2 different mechanisms. Kinetic studies gave support for the mechanism involving a reversible energy-transfer step as a reaction competing with the oxetane formation. The data implied, however, that the difference in triplet energies of propiophenone and acetophenone is much smaller than the reported values, which were derived from the phosphorescence spectra in glasses. This apparent contradiction was eliminated by establishing that both ketone triplets in benzene at room temperature are practically isoenergetic. This was concluded from a chem. kinetic study based on competing oxetane formation from both ketones with 2-methyl-2-butene. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1COA of Formula: C10H8O3).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.COA of Formula: C10H8O3
