AB - In general, organic strong bases and precious metal complexes serve as catalysts in the dehydrogenative coupling reaction of silanes with alcohols. However, these catalysts can't be easily separated from the catalytic system. Moreover, the self‐polymerization of silanes usually occurs in the presence of strong bases. In this work, utilizing the coordination of imidazolium nitrogen with Pd metal nanoparticles, the alkaline imidazole‐functionalized porous organic polymer stabilized palladium nanoparticles (Pd/PDVB‐Vim) is developed to compensate for the above‐mentioned drawbacks. The Pd/PDVB‐Vim catalyst is characterized and applied in the dehydrogenative coupling reaction of silanes with alcohols under mild conditions (30 °C). The characterization results demonstrate the Pd NPs are uniformly dispersed on PDVB‐Vim with ultrasmall particle size (Ca. 2.00 nm) and the strong interaction of the nitrogen on PDVB‐Vim and Pd NPs is obvious in Pd/PDVB‐Vim. This strong interaction makes the Pd/PDVB‐Vim catalyst exhibits the best stability and reusability.
