And the article was published in Science (Washington, DC, United States) in 2019. Product Details of 623-00-7 The author mentioned the following in the article:
In photoredox catalysis, an excited chromophore typically activates a single reactant either by oxidizing or reducing it. Ghosh et al. used a semiconductor catalyst to activate two reactants at once by quenching both an excited electron and the residual pos. hole (see the Perspective by Swift). As such, two different reactive carbon or halide fragments could be appended to sep. sites on an aryl ring. The catalyst also tolerated strong nucleophiles such as cyanide and could be recovered easily and reused. The results came from multiple reactions, including the reaction of 4-Bromobenzonitrile(cas: 623-00-7Product Details of 623-00-7)
4-Bromobenzonitrile(cas: 623-00-7) is classified as organic nitriles, which are commonly use solvents and are reacted further for various applications such as manufacture of polymers and intermediates for pharmaceuticals and other organic chemicals,Product Details of 623-00-7 It can also be used as an aryl halide test compound in developing greener reaction conditions for Suzuki cross-coupling between aryl halides and phenyl boronic acid.
