采用质子酸对稳定分子氮络合物进行还原质子化反应的研究,从1975年Chatt的工作算起,已有8年的历史了,深入的工作仍在继续进行中。1979年我们采用了金属氢化物既可作为氢源、又可当作还原剂,开展了与稳定及不稳定分子氮络合物反应的研究,并取得了一些初步有趣的结果。采用的分子氮络合物有[Mo(N_2)_2(dppe)_2](Ⅰ)和[Ti(O-i-Pr)_4—NaNp—N_2](Ⅱ)固氮体系。金属氢化物有NaFeH(CO)_4(Ⅲ),H_2Fe(CO)_4,(η~5-C_5H_5)_2ZrH_2和(η~5-C_5H_5)_2Zr(H)C1。实验结
The study on the reduction protonation of stable molecular nitrogen complexes by proton acids has been going on for eight years since Chatt’s work in 1975. In-depth work is still going on. In 1979, we used metal hydride as both a hydrogen source and a reductant to study the reaction with stable and unstable molecular nitrogen complexes. We also obtained some preliminary and interesting results. The molecular nitrogen complexes used were [Mo (N_2) _2 (dppe) _2] (Ⅰ) and [Ti (O-i-Pr) _4-NaNp-N_2] (Ⅱ) The metal hydrides include NaFeH (CO) 4 (Ⅲ), H 2 Fe (CO) 4, (η 5-C 5 H 5) 2 ZrH 2 and (η 5-C 5 H 5) 2 Zr (H) Cl.
