  Complexes 1 and 2 do not react with H(2), N(2), or 3,3-dimethyl-but-1-ene. Treatment of 1 with 1 equiv of NaHBEt(3) in C(6)D(6) gives a mixture of new trihydrides (PPh(3))HRu(&mgr;-Cl)(&mgr;-H)(&mgr;-PMe(2)Cp)(2)ZrH (3) and (PPh(3))HRu(&mgr;-H)(2)(&mgr;-PMe(2)Cp)(2)ZrCl (4). Complex 3 transforms to 4 upon standing in solution for a period of several days. Under the same conditions, complex 2 leads smoothly

  pathways whose relative contribution depends on the nature of R and X. The most direct pathway involves regiospecific protonation at the β-carbon of the vinylidene. However, under some conditions initial protonation at the metal to form [Re(H)X(CCHR)(dppe)2]+ is more rapid, and this hydride subsquently rearranges to form the carbyne by an intramolecular pathway or by protonation of [Re(H)X(CCHR)(dppe)2]+

  The trivalent yttrium tuck-over hydride complex, (C5Me5)(2)Y(mu-H)(mu-eta(1):eta(5)-CH2C5Me4)Y(C5Me5), 1, acts as a reductant in reactions in which the (mu-H)(-) hydride ligand and the bridging Y-C alkyl anion linkage in the mu-eta(1):eta(5)-CH2C5Me4)(2-) ligand combine to form a C-H bond in (C5Me5)(-) and deliver two electrons to a substrate. Complex 1 reacts with PhSSPh, AgOTf (OTf = OSO2CF3), and Et3NHBPh4 to form [(C5Me5)(2)Y(mu-SPh)](2), [(C5Me5)(2)Y(mu-OTf)](2), and (C5Me5)(2)Y(mu-Ph)(2)BPh2, respectively. The reactivity of the Y-H and Y-CH2C5Me4 linkages in 1 was probed via carbodiimide insertion reactions. (PrN)-Pr-i=C=(NPr)-Pr-i inserts into both Y-H and Y-C bonds to yield (C5Me5)[(PrNC)-Pr-i(H)(NPr)-Pr-i]Ymu-eta(5)-C5Me4CH2[(PrNCNPr)-Pr-i-Pr-i]}Y(C5Me5)(2). Carbodiimide insertion with [(C5Me5)(2)YH](2), 2, was also examined for comparison, and (C5Me5)(2)Y[(PrNC)-Pr-i(H)(NPr)-Pr-i-kappa N-2,N'] was isolated and structurally characterized. To examine the possibility of selective reactivity of the bridging ligands, mu-H versus mu-CH2C5Me4, trimethylsilylchloride was reacted with 1, and the tuck-over chloride complex, (C5Me5)(2)Y(mu-Cl)(mu-eta(1):eta(5)-CH2C5Me4)Y(C5Me5), was isolated.

  Examination of the Y[N(SiMe3)(2)](3)/KC8 reduction system that allowed isolation of the (N-2)(3-) radical has led to the first evidence of Y2+ in solution. The deep-blue solutions obtained from Y[N(SiMe3)(2)](3) and KC8 in THF at -35 degrees C under argon have EPR spectra containing a doublet at g(iso) = 1.976 with a 110 G hyperfine coupling constant. The solutions react with N-2 to generate (N-2)(2-) and (N-2)(3-) complexes [(Me3Si)(2)N](2)(THF)Y}(2)(mu-eta(2):eta(2)-N-2) (1) and [(Me3Si)(2)N](2)(THF)Y}(2)(mu-eta(2):eta(2)-N-2)[K(THF)(6)] (2), respectively, and demonstrate that the Y[N(SiMe3)(2)](3)/KC8 reaction can proceed through an Y2+ intermediate. The reactivity of (N-2)(3-) radical with proton sources was probed for the first time for comparison with the (N-2)(2-) and (N-2)(4-) chemistry. Complex 2 reacts with [Et3NH] [BPh4] to form [(Me3Si)(2)N](2)(THF)Y}(2)(mu-N2H2), the first lanthanide (N2H2)(2-) complex derived from dinitrogen, as well as 1 as a byproduct, consistent with radical disproportionation reactivity.
