化合物WCl_2（PMe_3）_4与邻苯二胺（1，2-二氨基苯）在四甲苯中发生氧化加成反应，生成亚胺钨配合物mer-W（o-NC_6 H_4 NH_2）Cl_2（PMe_3）_3（1）。1与NaBPh 4发生氯化物取代反应，生成七配位钨（VI）配合物{WCl[o-（HN）2C 6 H4]2（PMe 3）2}（BPh 4）（2）。MoOCl_2（PMePh_2）_3与邻苯二胺在碱（Et_3N）存在下反应，生成一种亚胺络合物trans-Mo（o-NC_6 H_4 NH_2）Cl_3（PMePh_2）_2（3）。测定了标题化合物的X-射线结构。在1和3中，假八面体配合物含有来自邻苯二胺配体的单齿近线性亚氨基，而在配合物2中，几何构型为扭曲的八面体，具有螯合基团（HN）2C 6 H4。
The compound WCl2(PMe3)4undergoes an oxidative-addition reaction with excesso-phenylenediamine (1,2-diaminobenzene) in refluxing toluene to give the tungsten(IV) imido complexcis,mer-W(o-NC6H4NH2)Cl2(PMe3)3(1). A chloride substitution reaction of1with NaBPh4leads to the seven-coordinate tungsten(VI) complex {WCl[o-(HN)2C6H4]2(PMe3)2}(BPh4) (2). Interaction of MoOCl2(PMePh2)3with excesso-phenylenediamine in the presence of base (Et3N) gives the imido complexmer,trans-Mo(o-NC6H4NH2)Cl3(PMePh2)2(3). X-ray structures of the compounds listed in the title have been determined. In1and3the pseudo-octahedral complexes contain unidentate nearlinear imido groups, derived from theo-phenylenediamine ligand, whereas in complex2the geometry is distorted capped octahedral with chelating (HN)2C6H4groups.
