The author of 《Sulfuryl Fluoride Mediated Conversion of Aldehydes to Nitriles》 were Gurjar, Jitendra; Bater, Jorick; Fokin, Valery V.. And the article was published in Chemistry – A European Journal in 2019. Electric Literature of C7H4BrN The author mentioned the following in the article:
Aliphatic, aromatic, and heteroaromatic aldehydes were readily converted to corresponding nitriles in a one-pot reaction sequence with hydroxylamine and sulfuryl fluoride. The reaction proceeds at room temperature, does not require metal catalysts and special precautions, and produces nitriles in excellent yields. It is compatible with a variety of functional groups, can be performed in aqueous and organic solvents, and is readily scalable to multigram quantities. Mild conditions and high selectivity of the reaction enabled the construction of polyfunctional probes containing nitrile, alkyne, azide, and fluorosulfate groups for further orthogonal derivatization. The experimental part of the paper was very detailed, including the reaction process of 4-Bromobenzonitrile(cas: 623-00-7Electric Literature of C7H4BrN)
4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.Electric Literature of C7H4BrN 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.
