	abstract = {Molecular nitrogen is intrinsically unreactive, so much so that it has confounded chemists for decades in attempts to functionalize this abundant diatomic molecule. While biological systems and industrial processes can fix nitrogen to form ammonia, the challenge is to discover a process that involves a homogeneous catalyst that can utilize N-2 as a feedstock to generate higher value organonitrogen materials. In this review, the activation of molecular nitrogen by transition metal complexes is reviewed with the view to present new kinds of transformations for coordinated dinitrogen. Moreover, some reaction types that are as yet unknown are outlined to try and stimulate further research in this area. (C) 2003 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.},

	abstract = {The vibrational and electronic structure of the side-on N-2-bridged Zr complex [{(P2N2)Zr}(2)(u-n(2):n(2)-N-2)] (P2N2=PhP(CH2SiMe2NSiMe2CH2)(2)PPh) were analyzed. The vibrational characterization of the planar Zr2N2 core was based on resonance Raman and infrared spectroscopy. In the Raman spectrum, the N-N stretching band is found at 775 cm(-1) with an isotope shift of 22 cm(-1). Due to its appearance in many overtones and combination modes, the metal-metal stretch is assigned to the peak at 295 cm(-1). The two ungerade modes of the Zr2N2 core were identified in the infrared spectrum. Based on these four vibrations of the Zr2N2 unit, a quantum chemical assisted normal coordinate analysis (OCA-NCA) was performed. The force constants for the N-N and Zr-N bonds were calculated to be 1.53 and 2.58 mdyn Angstrom(-1), respectively. The butterfly distortion of the Zr2N2 unit obtained in DFT geometry optimizations of planar side-on N-2-bridged Zr complexes was analyzed in more detail. It was found that on bending of the Zr2N2 core, the lone pairs of the axial amide ligands are rotated by 90degrees. The bent Zr2N2 unit is 11 kcal mol(-1) lower in energy than the planar core due to a more uniform distribution of electron density between the metal atoms and NZ and delocalization of electron density from the amide ligands to the Zr2N2 unit. The spectroscopic implications of this distortion are analyzed.},

Stopped-flow kinetic data are consistent with a mechanism involving formation (within a k(1) step) of Ru-IV(TMP)(O)(OL) which then reversibly dissociates the OL ligand to generate Ru-IV(TMP)(O); this disproportionates to Ru-VI(TMP)(O)(2) and Ru-II(TMP), which forms Ru-II(TMP)(L). Delta H-1 double dagger values for the phosphine systems vary from 18 to 21 kJ mol(-1), increasing with decreasing electron density at the phosphorus, while Delta S-1 double dagger values become more favorable (-94 to -78 J mol(-1) K-1) with increasing molecular mass of the substituent. Preliminary kinetic data on the O-2-oxidations of the substrates catalyzed by (1) under 1 atm of air are presented.},
