terdentate cyclometalated complex [Pt (κ3-N,N,C-bpy6OMe-H)Cl]. Finally, reaction of Pd(II) and Au(III) derivatives invariably gave adduct species, with the exception of the dimeric complex [Pd(κ2-N,C-bpy6OMe-H) (OAc)]2, which, however, was not isolated in pure form. The reactivity of bpy6OMe, as emerged from this study, was compared with that of the corresponding disubstituted ligand 6,6′-dimethoxy-2,2′-bipyridine
6-甲氧基-2,2'-联吡啶(BPY的反应6OMe)与复合物中的富电子-铂(II)[PT(ME)2(DMSO)2〕得到的翻转环金属化配合物[铂(κ 2 -N, C-bpy 6OMe -H)(Me)(DMSO)]在温和的条件下。通过单晶X射线衍射结构测定证明了翻倒环金属化的发生。相反,bpy 6OMe与[Pt(Ph)2(DMSO)2 ]和[Pt(Cl)2(DMSO)2 ]在温和条件下的反应仅产生类型为[Pt(X)2(bpy 6OMe)的加合物。)](X = Ph,Cl)。下苛刻的条件,一个C的活化在甲氧基取代基H键,得到terdentate环金属化配合物[铂(κ 3 -N,N,C-BPY 6OMe -H)CL]。最后,加入Pd(II)和Au(III)的反应衍生物,得到总是加合物种类,与二聚复合物的异常[钯(κ 2 -N,C-BPY 6OMe -H)(OAC)] 2,然而, ,不是纯格式的。从这项研究中得出的bpy
