In 2019,Tetrahedron included an article by Uchida, Ko; Togo, Hideo. Computed Properties of C7H4BrN. The article was titled 《Transformation of aromatic bromides into aromatic nitriles with n-BuLi, pivalonitrile and iodine under metal cyanide-free conditions》. The information in the text is summarized as follows:
Various aromatic nitriles ArCN [Ar = Ph, 4-BrC6H4, 5-ethyl-2-furyl, etc.] were obtained in good yields by the treatment of aryl bromides with n-butyllithium and then pivalonitrile, followed by the treatment with mol. iodine at 70 °C, without metal cyanides under transition-metal-free conditions. The present reaction proceeded through the radical β-elimination of imino-nitrogen-centered radicals formed from the reactions of imines and N-iodoimines under warming conditions. The results came from multiple reactions, including the reaction of 4-Bromobenzonitrile(cas: 623-00-7Computed Properties of C7H4BrN)
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,Computed Properties 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.
