The iron(0) dinitrogen complexes [Fe(N2)(PP3)] (PP3 = P(CH2CH2PR2)3, R = Ph, iPr, Cy) were synthesized by reduction of the precursor chloro complexes with potassium graphite. On reaction with triflic acid, [Fe(N2)(PP3)] complexes afforded ammonia and hydrazine in yields of up to 23 and 16% respectively. The complex [Fe(N2)(PP3)] which has only been previously synthesized in situ, has now been isolated
铁 (0) 二氮配合物 [Fe(N2)(PP3)] (PP3 = P(CH2CH2PR2)3, R = Ph, iPr, Cy) 是通过用钾石墨还原前体氯配合物来合成的。在与三氟甲磺酸反应时,[Fe(N2)(PP3)] 络合物以分别高达 23% 和 16% 的产率提供氨和肼。以前仅在原位合成的复合物 [Fe(N2)(PP3)] 现在已被分离出来,并通过 15N NMR 光谱和 X 射线晶体学进行了充分表征。
