《The Dual Role of Benzophenone in Visible-Light/Nickel Photoredox-Catalyzed C-H Arylations: Hydrogen-Atom Transfer and Energy Transfer》 was written by Dewanji, Abhishek; Krach, Patricia E.; Rueping, Magnus. Application of 623-00-7This research focused ontoluene halobenzene nickel photoredox catalysis arylation; diphenylmethane preparation; C−H functionalization; atom transfer; benzophenone; energy transfer; metallaphotoredox. The article conveys some information:
A dual catalytic protocol for the direct arylation of non-activated C(sp3)-H bonds was developed. Upon photochem. excitation, the excited triplet state of a diaryl ketone photosensitizer abstracts a hydrogen atom from an aliphatic C-H bond. This inherent reactivity was exploited for the generation of benzylic radicals which subsequently enter a nickel catalytic cycle, accomplishing the benzylic arylation.4-Bromobenzonitrile(cas: 623-00-7Application of 623-00-7) was used in this study.
4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.Application 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.
