Efficient clay supported Pd nanoparticles as heterogeneous catalyst for arylation of alkenes

A new pincer-type ligand containing Pd(II) was immobilized on a modified bentonite. The material was evaluated as catalyst in the arylation of iodobenzene and several alkenes under room conditions. The catalyst combines high activity and selectivity, and can be reused three times with no observed deactivation.
