This work reported, green synthesis of palladium nanoparticles (Pd NPs) on the developed biodegradable microbeads as stabilizers, featuring chitosan, agarose and beta-cyclodextrin, investigation of the catalytic role of the Pd NPs prepared in the Suzuki-Miyaura and cyanation reactions. Pd NPs@microcapsules (CAP) converted a series of aryl halides to biphenyl compounds with yields ranging from 79 to 98%. Pd NPs@CAP was highly active in the cyanation of different aryl bromides and iodides using K4[Fe(CN)6] and was used to prepare benzonitriles with a yield of up to 97%. More importantly, Pd NPs@CAP was easily recovered from the reaction mixture and successfully reused seven consecutive times in the Suzuki-Miyaura and cyanation reactions. This significant features of Pd NPs@CAP were ease of purification of desired biaryls and benzonitriles and production of no byproducts in both catalytic reactions. In the experimental materials used by the author, we found 4-Bromobenzonitrile(cas: 623-00-7SDS of cas: 623-00-7)
4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.SDS of cas: 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.
