A new visible-light photocatalytic arylsulfonylation and bicyclization of C(sp3)-tethered 1,7-enynes with sulfinic acids has been developed, delivering functionalized sulfone-containing benzo[a]fluoren-5-ones, e.g., I with generally good yields. This eosin Y-catalyzed approach makes use of visible light as a safe and eco-friendly energy source to drive cascade cyclization reactions, resulting in continuous multiple bond-forming events including C-S and C-C bonds to efficiently construct polycyclic-linked alkyl aryl sulfones. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Product Details of 1186603-47-3).
5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Product Details of 1186603-47-3
