描述了 2-萘基双[双(二甲基膦基)乙烷]金属氢化物配合物 HMNp (dmpe) 2 (M= Fe、Ru 和 Os) 的制备和光谱表征。还描述了它们与 H2 反应生成二氢化物，以及与 CO、磷配体、烯烃、二取代乙炔和偶氮苯反应生成五配位零价物质。蒽与铁形成一种不寻常的四联二烯类络合物。 HFeNp (dmpe) 2 的大部分反应被认为是通过未检测到的中间体 Fe (dmpe) 2 进行的，Fe (dmpe) 2 是一种极其富含电子和反应性的物质；萘还原消除得到中间体的半衰期在 25°C 下约为 35 分钟。
The preparation and spectroscopic characterization of 2-naphthyl bis [bis (dimethylphosphino) ethane] metal hydride complexes HMNp (dmpe) 2 (M= Fe, Ru, and Os) are described. Also described are their reactions with H2 to give dihydrides and with CO, phosphorus ligands, olefins, disubstituted acetylenes, and azobenzene to give five-coordinate, zerovalent species. Anthracene forms an unusual tetrahapto diene-like complex with iron. Most of the reactions of HFeNp (dmpe) 2 are believed to proceed through the undetected intermediate Fe (dmpe) 2—an extremely electron-rich and reactive species; the half-life for reductive elimination of naphthalene to give the intermediate is about 35 min at 25 C.
