Palladium‐supported periodic mesoporous organosilica based on imidazolium ionic liquidframework (Pd@PMO‐IL) as an Efficient Catalyst for Heterogeneous Oxidative HeckReaction

Palladium‐supported periodic mesoporous organosilica with bridged imidazolium ionic liquidframework (Pd@PMO‐IL) obtained through the stabilization of catalytic Pd nanoparticles by imidazolium units.The catalyst presented a high activity and selectivity in the heterogeneous oxidative boron heck couplingreactions of various arylboronic acids with different olefins at very low catalyst loading and under mild reaction(base free) conditions. There is no observation of biphenyl- and other- byproducts in all reactions.
