Abstract
AbstractA series of carbosilane dendritic ligands of general formula Gn‐[CH(3,5‐Me2pz)2]m and their corresponding palladium(II) complexes Gn‐[CH(3,5‐Me2pz)2Pd(X)Cl]m (X = Cl or Me) containing four (m = 1) or eight (m = 2) terminal bis(pyrazolyl)methane moieties, along with their corresponding monometallic counterparts (m = 0), have been synthesized. An appropriate choice of poly(pyrazolyl)methane ligand has allowed us to overcome the steric and solubility issues that previously limited the synthesis of polymetallic dendrimers containing (scorpionato)palladium complexes. The evaluation of these complexes as catalyst precursors in the Heck reaction between p‐iodotoluene and methyl acrylate is also reported.
