  Activation of N2 by (silox)3Ta (1, silox = tBu3SiO) to afford (silox)3Ta═N−N═Ta(silox)3 (12-N2) does not occur despite ΔG°cald = −55.6 kcal/mol because of constraints of orbital symmetry, prompting efforts at an independent synthesis that included a study of REH2 activation (E = N, P, As). Oxidative addition of REH2 to 1 afforded (silox)3HTaEHR (2-NHR, R = H, Me, nBu, C6H4-p-X (X = H, Me, NMe2); 2-PHR

  The reaction of NbCl5 with (Me3Si)2NN(SiMe3)2, in the presence of tetrahydrofuran (thf) gives high yields (ca. 80%) of [NbCl3(thf)2}2N2](A); (A), or its tantalum analogue, reacts with Me3SiS2CNEt2 to give a high yield of the dinitrogen complexes with exclusively sulphur co-ligands [M(S2CNEt2)3}2N2](M = Nb or Ta), and reaction of [MoCl4L2](L = MeCN or thf) with (Me3Si)2NN(SiMe3)2 gives [MoCl3L3] in high yield, together with N2.

  在四氢呋喃（thf）存在下，NbCl5 与 (Me3Si)2NN(SiMe3)2 发生反应，得到高产率（约 80%）的 [NbCl3(thf)2}2N2](A)；80%）的[NbCl3(thf)2}2N2](A)；(A)或其钽类似物与 Me3SiS2CNEt2 反应，可得到高产率的二氮配合物，该配合物的配位体完全为硫[M(S2CNEt2)3}2N2]（M = Nb 或 Ta）；[MoCl4L2]（L = MeCN 或 thf）与 (Me3Si)2NN(SiMe3)2 反应，可得到高产率的[MoCl3L3]和 N2。

  Reduction of [P2N2]ZrCl2 (where P2N2 = PhP(CH2SiMe2NSiMe2CH2)(2)PPh) by KC8 under N-2 generates the dinuclear dinitrogen complex ([P2N2]Zr)(2)(mu-eta(2):eta(2)-N-2) and impurities in varying yields depending on the solvent and temperature. The toluene complex [P2N2]Zr(eta(6)-C7H8) along with a dinuclear species with bridging PC6H5 groups is observable. Also observable in the crude reaction mixtures is the mu-oxodiazenido derivative, ([P2N2]Zr)(2)(mu-eta(2):eta(2)-N2H2)(mu-O), due to reaction with trace H2O. This paper reports the full details of the preparation of ([P2N2]Zr)(2)(mu-eta(2):eta(2)-N-2) including an improved method that involves reduction at low temperatures in a tetrahydrofuran solvent. Also reported is a reproducible synthesis of the oxodiazenido complex along with the X-ray structures of the dinitrogen complex and the oxodiazenido derivative.
