Fluorapatite-supported palladium catalyzed C=C bond cleavage of α, β-unsaturated ketones to alkenyl nitriles is presented. The reaction was performed with different basic catalysts, such as hydroxyapatite (HAP), fluorapatite (FAP), tert-butoxyapatite (TBAP), and MgÀ AlÀ HT derived oxide. Later, fluorapatite-supported palladium (PdFAP) catalyst was prepared by treatment of fluorapatite with bis(benzonitrile) palladium(II) chloride. PdFAP catalyst was characterized by XRD, TEM, BET, CHN analysis, ICP-AES and FTIR. The average particle size of the palladium particles in the PdFAP catalyst was found in the range of 35-45 nm. The reaction to synthesize cinnamonitrile from cinnamoyl pyrrole and acetonitrile was optimized at 383 K for 6 h using a toluenecyclohexane solvent system with 95% conversion and 90% selectivity. A kinetic model was also developed. The catalyst was recovered and reused for three cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
