And the article was published in Microporous and Mesoporous Materials in 2019. Synthetic Route of C7H4BrN The author mentioned the following in the article:
Palladium nanorods (PdNRs) into mesoporous channels of SBA-15 nanocatalyst (PdNRs/SBA-15) were synthesized by a green and surfactant-free ultrasonic method without any surfactants and complex chem. modification and chem. method in absence of ultrasound, resp. The PdNRs/SBA-15 catalysts were characterized by XRD, TEM, XPS, N2 absorption-desorption and FT-IR anal. The results showed that PdNRs with 15.96 ± 3.89 nm long and 5.69 nm wide were highly dispersed into mesoporous channels exploiting the confinement effect of SBA-15 pore channel, while reunited PdNPs were distributed on the outside surface of SBA-15 in PdNPs/SBA-15 prepared by chem. method. The in-situ ultrasonic reduction of PdNRs/SBA-15 by the reductive radical (induced by ultrasonic process) was good for higher dispersion of Pd species and the formation of Pd species inside the mesoporous channel of SBA-15 without any structure-directing agents or surfactants. The yield of Suzuki coupling reaction between 4-bromotoluene and phenylboronic acid catalyzed by PdNRs (5)/SBA-15 reached 96.4%, which was much higher than that of PdNPs(5)/SBA-15 prepared without ultrasound (76.3%). PdNRs (5)/SBA-15 could be reused up to five times without a significant activity loss due to the strong chem. interaction and the unblocked channel. The experimental part of the paper was very detailed, including the reaction process of 4-Bromobenzonitrile(cas: 623-00-7Synthetic Route of C7H4BrN)
4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.Synthetic Route 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.
