Description
Summary:[Display omitted] •Pd@KAPs(Ph-PPh3) exhibits high alkoxycarbonylation activity.•Alkoxycarbonylation of aryl iodides was tested under balloon pressure of CO.•Moderate to excellent yields of benzoic esters were obtained.•Pd@KAPs(Ph-PPh3) is reused up to 10 times with negligible palladium leaching. An efficient method for the alkoxycarbonylation of aryl iodides using palladium supported on triphenylphosphine functionalized porous organic polymer (Pd@KAPs(Ph-PPh3)) as the catalyst is reported. Under balloon pressure of CO, various aryl iodides on carbonylation with alcohols and phenols give the corresponding products in moderate to excellent yields (74–96%). The catalyst can be easily separated by simple filtration process and recycled up to ten times without significant decrease in activity. The salient features of this protocol are the simplicity in handling of the catalyst, low CO pressure, negligible palladium leaching and good catalyst recyclability.
