Stability or flexibility: Metal nanoparticles supported over cross-linked functional polymers as catalytic active sites for hydrogenation and carbonylation
substrate to Pt ratio of 4000 under mild reactions. Pd/CFP was the catalyst for carbonylation of aryl iodides in the presence of secondary amines and acylhydrazines. Doublecarbonylation with secondary amines produced α-ketoamides with the selectivity of 80%. Diacylhydrazine molecules were synthesized by the direct carbonylation of aryl iodide with acylhydrazine over Pd/CFP. The recyclability and recoverability

To provide a crosslinkable fluorinated elastomer composition which is excellent in crosslinking reactivity and of which a crosslinked product is excellent in heat resistance and chemical resistance. The crosslinkable fluorinated elastomer composition comprises a fluorinated elastomer (e.g. a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer) and an aromatic compound having at least two crosslinkable unsaturated double bonds (e.g. a compound represented by the formula (A-1)), and the crosslinked product is one obtained by crosslinking the crosslinkable fluorinated elastomer composition.
