Heterogeneous Pd/POSS Nanocatalysts for C-C Cross-Coupling Reactions

An insoluble solid support of N −heterocyclic imidazolium‐functionalized cage‐like silsesquioxane (SQ); Bim‐SQ, was synthesized by nucleophilic substitution of octakis(3‐chloropropyl)octasilsesquioxane with an excess bis‐(imidazol‐1‐yl)methane and investigated as a new organic‐inorganic hybrid support. In the presence of Bim‐SQ, Pd(II) from [PdCl 4 ] 2− can be stabilized via both electrostatic interactions and imidazole‐ N ‐coordination, giving...
