Cleavage of the relatively inert dinitrogen (N(2)) molecule, with its extremely strong N identical withN triple bond, has represented a major challenge to the development of N(2) chemistry. This report describes the reductive cleavage of N(2) to two nitrido (N(3-)) ligands in its reaction with Mo(NRAr)(3), where R is C(CD(3))(2)CH(3) and Ar is 3,5-C(6)H(3)(CH(3))(2'), a synthetic three-coordinate molybdenum(III) complex of known structure. The formation of an intermediate complex was observed spectroscopically, and its conversion (with N identical withN bond cleavage) to the nitrido molybdenum(VI) product N identical withMo(NRAr)(3) followed first-order kinetics at 30 degrees C. It is proposed that the cleavage reaction proceeds by way of an intermediate complex in which N(2) bridges two molybdenum centers.
将惰性的氮气（N2）分子裂解，使其具有极强的 N≡N 三重键，这一直是开发 N2 化学的主要挑战。本报告描述了氮气（N2）与 Mo（NRAr）3 的反应中，通过还原裂解生成两个氮化物（N3-）配体，其中 R 是 C（CD3）（2）CH3，Ar 是 3,5-C6H3（CH3）2'，这是一种已知结构的合成三配位钼（III）配合物。通过光谱观察到中间配合物的形成，其转化（伴随着 N≡N 键的裂解）为氮化物钼（VI）产物 N≡Mo（NRAr）3，遵循 30°C 下的一级动力学。据推测，裂解反应通过 N2 桥接两个钼中心的中间配合物进行。
