The article was titled 《Tandem [2 + 2] Cycloaddition/Rearrangement toward Carbazoles by Visible-Light Photocatalysis》.Product Details of 399-52-0 The article contains the following contents:
Reported herein is the first example of the synthesis of carbazoles via oxidative cyclization of 3-alkenylindoles with styrenes under visible light. The irradiation of a catalytic amount of [Ir(dtbbpy)(ppy)2][PF6] as the photocatalyst enables various 3-alkenylindoles and styrenes to undergo tandem [2 + 2] cycloaddition/rearrangement, thereby leading to carbazole derivatives in good to excellent yields under aerobic conditions. Mechanistic studies reveal that photoinduced energy transfer followed by electron transfer is responsible for the tandem reaction. In the experimental materials used by the author, we found 5-Fluoro-1H-indole(cas: 399-52-0Product Details of 399-52-0)
5-Fluoro-1H-indole(cas: 399-52-0) is a member of aromaticfluorinated building blocks. Fluorine-containing aromatics have been incorporated into crop-protection chemicals (herbicides, insecticides, fungicides). Liquid crystals, positron emission tomography, and imaging systems represent new areas where fluoroaromatics and fluoroheterocyclics have gained attention.Product Details of 399-52-0
