[M（N_2）_2（dppe）_2][M = MO或W; dppe = 1，2-双（二苯基膦基）乙烷]与溴代烷、酰氯或芳酰氯在辐射下反应，得到有机肼基（2-）-和有机二氮烯基-配合物。配合物[ReCl（N2）（PMe 2 Ph）4]和[ReCl（N2）（py）（PMe 2 Ph）3]（py =吡啶）在二氮原子上能被酰化，但不能被烷基化，而在[OsCl 2（N2）（PMe 2 Ph）4]中，二氮原子甚至对酰氯无活性。配合物中二氮的反应活性沿着第三过渡系列按W > Re > Os的顺序降低。
The reactions of [M(N2)2(dppe)2][M = MO or W; dppe = 1,2-bis(diphenylphosphino)ethane] with alkyl bromides, acyl chlorides, or aroyl chlorides, under irradiation, lead to organohydrazido(2–)- and organodiazenido-complexes. Complexes [ReCl(N2)(PMe2Ph)4] and [ReCl(N2)(py)(PMe2Ph)3](py = pyridine) can be acylated but not alkylated at the dinitrogen, but in [OsCl2(N2)(PMe2Ph)4] dinitrogen is inactive even to acid chlorides. The reactivity of dinitrogen in its complexes decreases along the third Transition Series in the order W > Re > Os.
