Özet
This work reports i) green synthesis of palladium nanoparticles (Pd NPs) on the developed biodegradable microbeads as stabilizers, featuring chitosan, agarose and beta-cyclodextrin, ii) investigation of the catalytic role of the Pd NPs prepared in the Suzuki-Miyaura and iii) cyanation reactions. Pd NPs@microcapsules (CAP) convert a series of aryl halides to biphenyl compounds with yields ranging from 79 to 98%. Pd NPs@CAP is highly active in the cyanation of different aryl bromides and iodides using K4[Fe(CN)6] and is used to prepare benzonitriles with a yield of up to 97%. More importantly, Pd NPs@CAP is 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 are i) ease of purification of desired biaryls and benzonitriles and ii) production of no by-products in both catalytic reactions
