In 3, only the isomer in which the methyl ligand is trans to nitrogen is formed. In the related complex [Pd(η3-C3H5)(NOPONMe2-N,P)]Cl, 7, an equilibrium has been evidenced between 7a and 7b, which
新的,结构表征的配体双(恶唑啉)苯基亚膦酸酯(I,缩写为NOPON Me 2)的配位化学显示出其柔性,这是由于可能形成六元螯合环。在加入Pd(II)配合物[钯(NCMe)(NOPON我2 - N,P,N)](BF 4)2,1(在其特征在于,X射线衍射1 ·0.5Et 2 O·0.33MeCN),和[PdCl(NOPON Me 2 - N,P,N)](PF 6),2,该配体以静态三齿方式表现,而在[Pd(Me)Cl(NOPONMe 2 - N,P)],3,[ PdI 2(NOPON Me 2 - N,P)],4,[PdCl 2(NOPON Me 2 - N,P)],5和烯丙基络合物[Pd( η 3 -C 3 H ^ 5)(NOPON我2 - N,P)](PF 6),6,它显示fluxional二齿行为,如通过可变温度NMR研究。在3,仅形成其中甲基配体转化为氮的异构体。在相关络合物[将Pd(η
