The manuscript describes a method, which ensures a selective functionalization of the mesopore surface with a clickable linker and thus makes it possible to study confinement effects during catalyzed reactions. First, the silanol groups on the particle surface and in the pore entrances of the SBA-15 are passivated. By solvent extraction, the template is removed and afterwards the pore walls are functionalized with 3-azidopropyltriethoxysilane before the catalyst is clicked on the pore walls. In initial experiments of asymmetric Rh-catalyzed 1,2-addition, the performance of a catalyst clicked selectively on the mesopore walls is investigated.
