	abstract = {Rotational spectra of OC-AuX (X = F, Cl, Br) have been measured in the frequency range 5-21 GHz, using a pulsed jet cavity Fourier transform microwave spectrometer. The molecules were prepared by ablating. Au metal with a Nd:YAG laser and allowing the vapor to react with CO plus a halide precursor contained in the Ar backing gas of the jets. For OC-AuCl and OC-AuBr these are I the first high-resolution spectroscopic measurements; for OC-AuF these are the first observations of any kind. Ail three molecules are linear. Rotational constants, centrifugal distortion constants, and nuclear quadrupole coupling constants have been precisely evaluated. The geometries determined for all three molecules show CO bond lengths close to that of free CO, plus relatively long Au-C bonds. These results are corroborated by ab initio calculations, which have also produced Mulliken populations showing significant sigma -donation from CO to Au, plus some pi -back-donation from An to CO. There are major changes in the Au, Cl, and Br nuclear quadrupole coupling constants when CO bonds to AuX, consistent with the formation of strong Au-C bonds. The structural properties of OC-AuF are somewhat different from those of OC-AuCl and OC-AuBr.},

	abstract = {This paper deals with the organometallic chemistry of the trivalent second-row transition metals of groups 4-6, namely, Zr, Nb, and Mo, with the cyclopentadienyldiphosphine ligand [eta(5)-C5H3-1,3-(SiMe2CH2PR2)(2)], abbreviated as [(P2Cp)-P-R] (where R = i-Pr and Ph). The Zr(IV) complex [i-PrP2Cp]ZrCl3 undergoes reduction with Na/Hg to form the trivalent Zr derivative, [i-PrP2Cp]ZrCl2, which undergoes a metathetical reaction with MeMgBr to yield the monomethyl derivative [i-PrP2Cp]Zr(CH3)Cl. The reaction of the Zr(III) complex [i-PrP2Cp]ZrCl2 with excess carbon monoxide results in disproportionation to the Zr(IV) complex, [i-PrP2Cp]ZrCl3, and the Zr(II) compound [i-PrP2Cp]Zr(CO)(2)Cl. This reaction is reversible, and upon removal of CO the starting material, [i-PrP2Cp]ZrCl2 is formed. The preparation of the diamagnetic Nb(III) complex [(P2Cp)-P-R]NbCl2 is achieved by the reaction of NbCl3(DME) with [(P2Cp)-P-R]Li. [(P2Cp)-P-R]NbCl2 complexes react with excess CO to form the CO adducts whose solid-state structures have been determined. The Nb(IV) derivatives [(P2Cp)-P-R]NbCl3 are formed via the reaction of [(P2Cp)-P-R]NbCl2 with PbCl2. These complexes can also be produced when Nb(O)Cl-3(THF)(2) is allowed to react with excess [(P2Cp)-P-R]Li. These Nb(IV) derivatives are ESR active, and their solid-state molecular structures show distorted octahedral geometries around the Nb center. MoCl3(THF)(3) reacts with [(P2Cp)-P-R]Li to generate the corresponding Mo(III) complexes [(P2Cp)-P-R]MoCl2. These compounds are low-spin, paramagnetic complexes as evidenced by their ESR spectra.},

	abstract = {The gas-phase ion chemistry of eta(6)-cycloheptatriene chromium tricarbonyl was studied by Fourier transform ion cyclotron resonance spectroscopy. The well-known trend that fragment-ion reactivity toward the parent neutral increases with increasing electron deficiency on the metal atom was, in general, observed. However, the reactivity of the fragment ions from (eta(6)-c-C7H8)Cr(CO)(3) shows the order Cr+ > C5H6Cr+ > C7H8Cr+ approximate to C7H8Cr(CO)(+) > C7H8Cr(CO)(2)(+) > C7H8Cr(CO)(3)(+), in which C7H8Cr+ has an anomalously low reactivity. Similarly, the secondary ion-molecule product ion, (C7H8Cr)(2)(+), has an anomalously low reactivity when compared with that of (C7H8Cr)(2)(CO)(3)(+). A more quantitative analysis indicates that the ions C7H8Cr+, C7H8Cr2(CO)(+) and C7H8Cr2(CO)(2)(+) are less reactive than expected. All of these low reactivities can be explained by a beta-hydride shift from the cycloheptatriene ring to the chromium atom that converts the cycloheptatriene ligand into an aromatic tropylium ligand. The coordination hapticity to chromium changes from eta(6) to eta(7) + eta(1) and the electron deficiency of chromium drops by 2. Similarly, the reactivity of the fragment ion C5H6Cr+ implies it has a hydrido-pi-cyclopentadienyl structure. An additional driving force for these rearrangements appears to be the aromatization of the seven-membered cycloheptatriene ring to a tropylium ring and the aromatization of the five-membered cyclopentadiene ring to a cyclopentadienyl ring, as the fragment and secondary ion reactivity orders are normal in the otherwise analogous benzene chromium tricarbonyl and cyclopentadienyl vanadium tetracarbonyl systems. These latter systems have no possible corresponding aromatization reaction. Ions that have low reactivity and have metal-hydrogen bonds react with deuterium-labeled methanol to eliminate a molecule of molecular hydrogen in which one hydrogen atom comes from the hydroxyl group of methanol and the other hydrogen atom comes from the organometallic ion. In contrast, ions that have normal reactivity and do not have metal-hydrogen bonds give methanol adduct products when reacted with methanol.},
