The first phosphine-free Pd-catalysed double carbonylation of aryl iodides is reported as a general and practical method, giving excellent conversions and selectivities for a wide range of aryl iodides and amine nucleophiles under atmospheric CO pressure.
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

the synthesis of amides via palladium‐catalysed aminocarbonylation of aryliodides is reported using the bulky cis‐1,2‐bis[(di‐tert‐butylphosphino)methyl]cyclohexane ligand under atmospheric pressure of carbon monoxide. Excellent conversions (up to 99%) and chemoselectivities (up to 99%) were obtained for a range of aryliodides and amine nucleophiles. The effect of the substituents on the substrate
