In 2019,Organic Letters included an article by Liao, Jennie; Basch, Corey H.; Hoerrner, Megan E.; Talley, Michael R.; Boscoe, Brian P.; Tucker, Joseph W.; Garnsey, Michelle R.; Watson, Mary P.. Quality Control of 4-Bromobenzonitrile. The article was titled 《Deaminative Reductive Cross-Electrophile Couplings of Alkylpyridinium Salts and Aryl Bromides》. The information in the text is summarized as follows:
A nickel-catalyzed reductive cross-coupling of alkylpyridinium salts and aryl bromides has been developed using Mn as the reductant. Both primary and secondary alkylpyridinium salts can be used, and high functional group and heterocycle tolerance is observed, including for protic groups. Mechanistic studies indicate the formation of an alkyl radical, and controlling its fate was key to the success of this reaction. In the experiment, the researchers used 4-Bromobenzonitrile(cas: 623-00-7Quality Control 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,Quality Control 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.
