The reaction was monitored by multinuclear NMR spectroscopy and showed the formation of a number of intermediates. The final product is a hydride-bridged imidoamido silyated species that has the imido bridging between the two central tantalum atoms. The origin of the bridging hydrides in the product is likely to arise from the excess silane present, on the basis of labeling studies.</p>},

	abstract = {Reaction of phenylacetylene with the dinuclear tetrahydride complex ([NPN]Ta)(2)(mu-H)(4) gives the product ([NPN]Ta)(2)(mu-PhCCH)(mu-H)(2) (where NPN is PhP(CH2SiMe2NPh)(2)). Activation of other terminal alkynes by ([NPN]Ta)(2)(mu-H)(4) accesses ([NPN]Ta)(2)(mu-RCCH)(mu-H)(2) (R = n-Pr, t-Bu). Crystallographic analysis of the R = Ph derivative showed it to be a bis(mu-alkylidene) bound asymmetrically to the two tantalum centres. Storage of solutions of ([NPN]Ta)(2)(mu-PhCCH)(mu-H)(2) under vacuum promotes the loss of H-2 and cleavage of the C-C bond to give a bis(mu-alkylidyne) complex, ([NPN]Ta)(2)(mu-CPh)(mu-CH). Addition of diphenylacetylene did not give the desired ([NPN]Ta)(2)(mu-CPh)(2), but rather promotes a complex decomposition of the supporting [NPN] ligands. Reaction of phenylacetylene with the dinitrogen complex ([NPN]Ta)(2)(mu-eta(1):eta(2)-N-2)(mu-H)(2) results in the dissociation of the bound dinitrogen and the formation of ([NPN]Ta)(2)(mu-PhCCH)(mu-H)(2), which is identical to that derived from the reaction with the dinuclear tetrahydride.},

	abstract = {The dinuclear tantalum tetrahydride complexes ((RPh)[NPN]Ta)(2)(mu-H)(4) ([NPN] = (PhNSiMe2CH2)(2)PR; R = Ph, Cy) promote the asymmetric activation of molecular nitrogen to form ((RPh)[NPN]Ta)(2)(mu-eta(1):eta(2)-N-2)(mu-H)(2). The coordinatively unsaturated dinuclear dihydride, ((RPh)[NPN]Ta)(2)(mu-H)(2), has been proposed as the reactive intermediate, with a tantalum-tantalum double bond storing four electrons with which to reduce N-2. Efforts to trap ((CyPh)[NPN]Ta)(2)(mu-H)(2) with excess PMe3 at low temperatures promoted the formation of a green product, proposed to be (CyPh [NPN]Ta(PMe3))(2)(mu-H)(2). Attempts to isolate this product promoted the orthometalation of an ancillary ligand N-Ph ring, forming (CyPh)[NPN]Ta(mu-H)(2)[mu-N(C6H4)]Ta[PN](H)(PMe3). Addition of 1 equiv of PMe3 to ((PhPh)[NPN] Ta)(2)(mu-H)(4) immediately produced the analogous orthometalation derivative, [NPN]Ta(mu-H)(2)[mu-N(C6H4)]Ta[PN](H)(PMe3).},
