Reactions of [(AMTTO)PdCl2]·MeOH (1) with sodium bromide and sodium iodide led to the palladacycles [(AMTTO)PdBr2]2·3.5THF (2) and [(AMTTO)PdI2]2·3MeOH (3) in excellent yields. Treatment of 2 and 3 with triphenyl-phosphane gave the complexes [(AMTTO)Pd(PPh3)Br]-Br·MeOH (4) and [(AMTTO)Pd(PPh3)I]·2MeOH (5), respectively. All the complexes have been characterized by IR spectroscopy, elemental analysis, as well as by X-ray diffraction studies. In addition, 4 and 5 have been characterized by 31p NMR spectroscopy.
