Xantphos or Xantphos chalcogenide complexes with general folmula [PdCl2(X∩X)] (where X = P, O, S or Se) were synthesized by the addition of corresponding ligands to [PdCl2(COD)] (COD = 1,5-cyclooctadiene). Prepared Complexes [PdCl2(Xantphos)] and [PdCl2(Xantphos = S)] showed distorted square planar geometries, from X-ray crystallographic analysis. All of the prepared complexes showed activity toward intermolecular
通过将相应的配体添加到[PdCl 2(COD)]中,合成具有普通薄膜[PdCl 2(X∩X)](其中X = P,O,S或Se)的Pd(II)Xantphos或Xantphos硫族化物配合物( COD = 1,5-环辛二烯)。通过X射线晶体学分析,制备的配合物[PdCl 2(Xantphos)]和[PdCl 2(Xantphos = S)]显示出扭曲的正方形平面几何形状。所有制备的络合物均显示出对异戊二烯与多种仲胺的分子间氢化胺化的活性。使用Pd–Xantphos作为催化剂可观察到吡咯烷的完全转化(〜100%)。当使用拥挤的仲胺时,氢化胺化反应表现出区域选择性。
