英文摘要: Abstract(#br)The synthesis of diphenylarylphosphane and 1,2-bis(diarylphosphanyl)ethane ligands, where the aryl group is –C 6 H 4 CH 2 CH 2 SiMe 2 CH 2 OC 6 H 4 -3-NMe 2 , their palladium(II) complexes, and their corresponding ammonium-quaternized derivatives is described. These new phosphanes were devised as models of potentially water-soluble dendritic carbosilane ligands, although the solubility brought about by the quaternized N -trimethylanilinium groups is scarce. The palladium(II) complexes have been fully characterized by 1 H, 13 C, and 31 P NMR spectroscopy and mass spectrometry, and have been tested in the Hiyama cross-coupling reaction between tri(methoxy)phenylsilane and 3-bromopyridine in aqueous sodium hydroxide solution.
