In 2022,Noten, Efrey A.; McAtee, Rory C.; Stephenson, Corey R. J. published an article in Chemical Science. The title of the article was 《Catalytic intramolecular aminoarylation of unactivated alkenes with aryl sulfonamides》.Recommanded Product: 1530-32-1 The author mentioned the following in the article:
In this work, an intramol. alkene aminoarylation cascade that exploits the electrophilicity of a nitrogen-centered radical to form a C-N bond, then repurposes the nitrogen atom’s sulfonyl activating group as a traceless linker to form a subsequent C-C bond was disclosed. This photoredox catalysis protocol enabled the preparation of densely substituted arylethylamines I [R1 = H, Me; R2 = H, Me, i-Pr, BrCH2CH2, Ph; R1R2 = H2COCH2, (CH2C)3, (CH2C)5; R3= 2-pyridyl, 2,6-di-FC6H3, 2,4,6-tri-ClC6H2, etc.] from com. abundant aryl sulfonamides and unactivated alkenes under mild conditions. Reaction optimization, scope, mechanism, and synthetic applications were discussed. In the experiment, the researchers used many compounds, for example, Ethyltriphenylphosphonium bromide(cas: 1530-32-1Recommanded Product: 1530-32-1)
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.Recommanded Product: 1530-32-1
