Abstract

Three aliphatic ligands are synthesized and fully characterized by IR, 1H and 13C NMR spectroscopy. These ligands react with a zerovalent compound Pd(dba)2 in the presence of methallyloxytris(dimethylamino)phosphonium hexafluorophosphate salt [C4H7OP(NMe2)3]+PF6– as an allylating agent for the synthesis of cationic η3-methallylpalladium complexes to give three cationic mononuclear η3-methallylpalladium complexes in high yields. These formed complexes are characterized by IR, 1H NMR and 13C NMR spectroscopy. One of them is characte­rized by X-ray diffraction. A DFT-optimized structure is also discussed.
