Manna, Kartic; Ganguly, Tanusree; Baitalik, Sujoy; Jana, Ranjan published the artcile< Visible-Light- and PPh3-Mediated Direct C-N Coupling of Nitroarenes and Boronic Acids at Ambient Temperature>, Electric Literature of 30095-98-8, the main research area is secondary amine photochem preparation triphenylphosphine mediator; nitroarene boronic acid intermol reductive amination.
Herein a metal-free, visible-light- and triphenylphosphine-mediated intermol., reductive amination between nitroarenes and boronic acids at ambient temperature without any photocatalyst is presented. Mechanistically, a slow reduction of nitroarenes to a nitroso and, finally, a nitrene intermediate occurs that leads to the amination product with concomitant 1,2-aryl/-alkyl migration from a boronate complex. A wide range of nitroarenes underwent C-N coupling with aryl-/alkylboronic acids providing high yields.
Organic Letters published new progress about Amination catalysts (photochem). 30095-98-8 belongs to class esters-buliding-blocks, and the molecular formula is C9H9NO4, Electric Literature of 30095-98-8.
