自从 Chatt 及其同事首次报道二氮复合物 cis-[W (N2) 2 (PMe2Ph) 4] 的质子分解产生氨 1、cis-[W (N2) 2 (PMe2Ph) 4] H+→ 2NH3+ N2+ 降解产物 (1) 以来，存在着一种令人着迷的可能性，即使用具有{MP4}-核心，M= Mo 或 W。作为避免核心氧化降解的一种手段，质子化与电子化的耦合显然很有吸引力2。我们在此描述了一个系统，该系统首次实现了这一目标，并构成了氨生产循环的基础，如图 1 中的方案 I。
Since Chatt and co-workers first reported that the protolysis of the dinitrogen complex cis-[W (N2) 2 (PMe2Ph) 4] gives ammonia1, cis-[W (N2) 2 (PMe2Ph) 4] H+→ 2NH3+ N2+ degradation products (1) there has existed the engaging possibility that a cyclic conversion of molecular nitrogen to ammonia might be achieved at room temperature and pressure using mediators possessing an {MP4}-core, M= Mo or W. As a means of circumventing oxidative degradation of the core, coupling protonation with electronation is clearly attractive2. We describe here a system in which this has been achieved for the first time and which forms the basis of an ammonia producing cycle, scheme I in Fig. 1.
