sulfoxide derivatives, which readily formed analogous pincer complexes with the PdII ions. The realization of κ3-S,N,X coordination (X = N or S) was confirmed by multinuclear NMR and IR spectroscopic data and, in some cases, X-ray crystallography. An unusual dynamic behavior of the 6,6-membered S,N,S complex with an organophosphorus ligand was additionally studied by the ROESY technique. All of the palladocycles
通过 2-(甲基硫烷基)苯甲酰氯与一系列带有辅助 N 或 S 供体的胺缩合,合成了新的多齿配体。在与 PdCl2(NCPh)2 的反应中,配体顺利地进行直接环钯化,得到具有 5,6-或 6,6-元稠合金属环的钳形配合物。硫化物配体用 H2O2 氧化得到相应的亚砜衍生物,它很容易与 PdII 离子形成类似的钳状复合物。κ3-S,N,X 配位(X = N 或 S)的实现通过多核 NMR 和 IR 光谱数据以及在某些情况下的 X 射线晶体学数据得到证实。ROESY 技术还研究了具有有机磷配体的 6,6 元 S,N,S 复合物的不寻常动态行为。
