Silver Triggering Activity of Heterogeneous Palladium Catalyst in Oxidative Carbonylation Reactions

A silver-triggered heterogeneous Pd-catalyzed oxi-dative carbonylation has been developed. This hetero-ge-neous pro-cess exhibited high efficiency, good recyclability, and was utilized for a one-pot construction of polycyclic compounds with multi-chiral cen--ters. AgOTf was used to remove chloride ions in the hetero-ge-neous catalyst Pd-AmP-CNC, generating a highly active Pd(II), which results in the high efficiency of the heterogeneous catalytic system.
