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 reactionseninfo:eu-repo/semantics/embargoedAccessAgaroseBenzonitrileBiphenylChitosanMicro BeadsPd NanoparticlesArticle148---31958557Q1WOS:000522094600057Q1
