Application In Synthesis of 4-Bromobenzonitrile The article mentions the following:
The synergistic combination of a heterogeneous organic semiconductor mesoporous graphitic carbon nitride (mpg-CN) and a homogeneous nickel catalyst with visible-light irradiation at room temperature affords the C(sp2)-C(sp3) cross-coupling of aryl halides and potassium alkyl trifluoroborates by single electron transmetallation. Like the homogeneously catalyzed protocol, the reaction is compatible with a variety of functional groups including electron-donating and electron-withdrawing aryl and heteroaryl moieties. Moreover, this protocol allows the installation of allyl groups onto (hetero)arenes, enlarging the scope of the method. The heterogeneous mpg-CN photocatalyst is easily recovered from the reaction mixture and reused several times, paving the way for larger-scale industrial applications of this type of photocatalytic bond-forming reactions. In the part of experimental materials, we found many familiar compounds, such as 4-Bromobenzonitrile(cas: 623-00-7Application In Synthesis of 4-Bromobenzonitrile)
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,Application In Synthesis of 4-Bromobenzonitrile 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.
