SNT has two independent surfaces, inner and outer, which can be differentially functionalized. Using thermal reduction, we prepared Pd-NP electively at the N-(3-Trimethoxysilylpropyl)dimethylenetriamine(DETA)-modified inner surface without ligand or stabilizer which are known to reduce the efficiency of Pd catalyst by limiting accessibility of substrates. We successfully applied this catalytic system in Suzuki coupling as well as direct arylation of thiazoles in water. Low catalyst loading (0.5 mol % Pd) and mild reaction conditions (60-80 oC) indicated the high catalytic activity of the current system. We confirmed that there is no catalyst leaching during the reaction, confirming that the reaction proceeds inside of SNT. Furthermore, after the reaction, Pd@SNT could be precipitated and a simple decantation allows separation of the catalyst.
