✦ Synopsis

Reactions of [(AMTTO)PdCl

2 ]•MeOH (1) with sodium bromide and sodium iodide led to the palladacycles [(AMTTO)PdBr 2 ] 2 •3.5THF (2) and [(AMTTO)PdI 2 ] 2 •3MeOH (3) in excellent yields. Treatment of 2 and 3 with triphenylphosphane gave the complexes [(AMTTO)Pd(PPh 3 )Br]-Br•MeOH (4) and [(AMTTO)Pd(PPh 3 )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 31 P NMR spectroscopy.
