The article was titled 《Visible light-promoted aerobic oxidative cleavage and cyclization of olefins to access 3-hydroxy-isoindolinones》, and you may find the article in Organic Chemistry Frontiers.Quality Control of Ethyltriphenylphosphonium bromide The information in the text is summarized as follows:
A convenient and environmentally friendly synthetic route from 2-vinylbenzimides to 3-hydroxy-isoindolinones through visible light-promoted transformations via iron/disulfide catalysis and mol. oxygen oxidation was developed. A range of 3-hydroxy-isoindolinones were obtained in moderate to good yields, which exhibited excellent functional group compatibility and broad substrate scope. Further mechanistic investigations proved that dioxetane might be a key intermediate being involved in the reaction. After reading the article, we found that the author used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Quality Control of Ethyltriphenylphosphonium bromide)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Quality Control of Ethyltriphenylphosphonium bromide
