A highly efficient heterogeneous catalytic system for Heck reactions with a palladium colloid layer reduced in situ in the channel of mesoporous silica materials.
A new catalyst, Pd-SBA, was prepared by the introduction of an Si-H function into the channel of SBA-15 mesoporous materials resulting in a highly dispersed metal colloid layer on the pore walls of the support material, creating one of the most active heterogeneous catalysts for Heck coupling reactions.
