  摘要：

  A multistep synthetic strategy enables the isolation of the niobaziridine-hydride complex Nb(H)(eta2-tBu(H)C=NAr)(N[Np]Ar)2 (1, Np = neopentyl, Ar = 3,5-C6H3Me2), which functions as a reactive synthon for its tautomer, the three-coordinate, trisamide species Nb(N[Np]Ar)3 (2). Treatment of 1 with various small molecules has demonstrated its capacity to effect two-electron reduction chemistry. Most noteworthy is the reaction between 1 and elemental phosphorus (P4), providing in high yield the bridging diphosphide complex (mu2:eta2,eta2-P2)[Nb(N[Np]Ar)3]2. However, unsaturated organic functionality including nitriles and aldehydes can insert into the Nb-H bond of 1, leaving the niobaziridine ring intact, thus demonstrating that dual pathways of reactivity are available to the niobaziridine-hydride functional group.

  Na[1a-N] with acid chloride substrates in tetrahydrofuran (THF) furnishes the corresponding organic nitriles concomitant with the formation of NaCl and the oxo niobium complex O[triple bond]Nb(N[Np]Ar)3 (1a-O). Utilization of 15N-labeled 15N2 gas in this chemistry affords a series of 15N-labeled organic nitriles establishing the utility of anion [1a-N]- as a reagent for the 15N-labeling of organic molecules

  通过末端氮化铌阴离子 [N[三键]Nb(N[Np]Ar)3]- ([1a- N]-，其中 Np = 新戊基和 Ar = 3,5-Me2C6H3) 通过等价 N 进行 O(Cl) 复分解交换。使用三酰胺钼系统 Mo(N[R]Ar)3 (R = t-Bu, 2a; R = Np, 2b) 作为反应，在异双核 N2 裂解反应中获得氮基阴离子 [1a-N]-伙伴。异双核桥接 N2 配合物 (Ar[R]N)3Mo-(mu-N2)Nb(N[Np]Ar)3 (R = t-Bu, 3b; R = Np, 3c) 与钠汞齐的还原断裂提供 1 当量的盐 Na[1a-N] 和中性 N[三键]Mo(N[R]Ar)3 (R = t-Bu, 2a-N; R = Np, 2b-N)。很容易实现 2-N 与 Na[1a-N] 的分离。在四氢呋喃 (THF) 中用酰氯底物处理盐 Na[1a-N] 会提供相应的有机腈，同时形成
