摘要：

The sterically bulky pyridinyl phosphine (Psimilar toN) ligands have been prepared from the phosphinylation of 2,4-di-tert-butyl-6- methylpyridine. Due to the steric hindrance, substitution reaction of these Psimilar toN ligands with (COD) PdMeCl yields the chloro-bridged dipalladium species [(Psimilar toN)(2)Pd2Me2Cl2], in which the Psimilar toN ligand acts as a monodentate. Treatment of these dimeric palladium compounds with AgBF4 in the presence of acetonitrile gives the corresponding C-H activation metal complex [(Psimilar toNsimilar toC) Pd(CH3CN)]BF4. Both spectral and X-ray single-crystal characterization of these palladium complexes are presented.
