The electronic properties of the resulting carbene complexes are similar and indicate that in the (phosphino)(amino)carbene the phosphine lone pair is not interacting with the carbene carbon and is available for further reactivity.},

Different substituents on the olefin dramatically influenced the reaction. While the chlorins were more reactive than the porphyrins (as free bases), the corresponding zinc complexes showed higher activity. The reaction mechanism was investigated, and an empirical model for selective CM was applied to our studies to direct further reactions.},

The overall objective was to learn more about the role of Ni2+ on the ZPO coating mechanism, particularly since this additive is believed to improve corrosion protection for the Al alloy. Secondary phosphates dominate the coatings when the Ni-containing solution is adjusted to starting pH values of either 3 or 5, while tertiary phosphate is predominant at pH 4. AlF3 precipitates during the early stages of the coating process. Ni2+ has two main roles in the mechanism. First, the rate of increase in local solution pH is retarded by the slower kinetics of reactions involving Ni2+ compared to Zn2+,leading to thinner ZPO coatings when Ni2+ is present in the coating solution. Second, most Ni2+ deposition occurs during the later stages of the coating process, by nickel phosphate deposition and/or by formation of a Ni-rich oxide. (c) 2006 Elsevier B.V.

The controlled/living nature of the polymerization is supported by linear first order plots (ln[M](o)/[M] versus time) and a linear increase of (M) over bar (n) versus conversion as well as low polydispersity. Similar controlled polymerization of methyl methacrylate was possible in acetonitrile. Up to 97\% of total copper used for polymerization could be removed from the polymer by simple precipitation in methanol and filtration.},

The cyclobutanols readily undergo retro-aldol reaction to give delta-ketoesters. The enantiomeric excess (ee) in the endo-cyclobutanols is measured by monitoring the ee in the ketoesters. Whereas in solution the ee in the product ketoester is zero, within achiral NaY zeolite, in the presence of a chiral inductor such as pseudoephedrine, ee{\textquoteright}s up to 28\% have been obtained. The influence of zeolite on several chiral esters of 2-benzoyladamantane-2-carboxylic acids has also been examined. Whereas in solution the diastereomeric excess is <15\%, in zeolite the delta-ketoesters are obtained in 79\% de (best examples). Ab initio computations suggest that enhancement of chiral induction within zeolites is likely to be due to cation complexation with the reactant ketone. Alkali ion-organic interaction, a powerful tool, is waiting to be fully exploited in photochemical and thermal reactions. In this context zeolites could be a useful medium as one could view them as a reservoir of "naked" alkali ions that are only partially coordinated to the zeolite walls.},

The starting materials, {[P2N2]M}(2)(mu -Cl)(2), (M = Y, Sm, Ho, Yb, Lu), are prepared by the reaction of syn-Li-2(dioxane)[P2N2] with MCl3(THF)(3) in toluene. The reactivity of these complexes toward PhLi and other arylating agents is dependent on the size of the M3+ ion. M = Y and Ho undergo C-C bond formation reactions to give biphenyldiide compounds {[P2N2]M}(2){mu-eta (6):eta (6 {\textquoteright})-(C6H5)(2)} and {[P2N2]Y}(2){mu-eta (6):eta (6 {\textquoteright})-(C6H4-p-Ph)(2)} These have been structurally characterized and show the biphenyl dianion bridging two [P2N2]M fragments. These [P2N2]M fragments migrate over the bridging ligand{\textquoteright}s pi -surface on the NMR time scale. M = Yb yields the paramagnetic monophenyl derivative [P2N2]Yb-(C6H5), where the Yb center is coordinatively unsaturated and resides in a distorted square-pyramidal environment. M = Lu results in a mixture of "ate" complexes of the formulation "[P2N2]LuPh . LiCl", as evidenced by Li-7 NMR. However, the biphenyl product {[P2N2]Lu}(2)-{mu-eta (6):eta (6 {\textquoteright})-(C6H5)(2)} can be synthesized via a reductive route. The presence of THF was found to be deleterious to the coupling reaction; in this case, the THF adduct [P2N2]Y(C6H4-p-Me)-(THF) was isolated and structurally characterized. The mechanism for the C-C bond formation reaction is described based on the isolation of these yttrium and lanthanide complexes.},

	abstract = {X-ray photoelectron spectroscopy (XPS) has been used to gain insight into surface reaction pathways associated with the nitridation by NH3 of MoO3 thin films grown on metallic substrates. The samples formed can be seen as model hydrodenitrogenation (HDN) catalysts, but the more-controlled surface morphology allows spectral features to be studied in the absence of charging effects that can interfere with such measurements on high-area samples. Observed core level and valence spectra are consistent with the MoO3 being reduced, but the degree of reduction depends on the reaction temperature. Heating to 350 degrees C indicates some conversion to Mo(+5) and {\textquoteright}O-rich{\textquoteright} Mo(+4) components, while heating to 450 degrees C and to 700 degrees C give respectively a {\textquoteright}N-rich{\textquoteright} Mo(+4) form and a Mo(+3) oxynitride as the dominant components. It is concluded that the nitridation of MoO3 by NH3 involves initial hydrogenation, with subsequent elimination of water, and the effective replacement of O by N as the reduction continues. Surface compositions determined here during the nitridation process contrast with conclusions reached previously for the evolution of bulk phases as deduced by X-ray diffraction.

	abstract = {Several anionic and paramagnetic [CpCr(NO)X-2](-) complexes (X = I [1], O3SCF3 (OTf) [2], Br [3], Cl [4]) have been prepared as potential precursors to neutral CpCr(NO)X-2 species. Reaction of [CpCr(NO)I](2) with [NBu4]I provides [NBu4][1], and halide abstraction from [NBu4][1] with 2 equiv of AgOTf affords [NBu4][2]. The weakly-bound OTf- ligands of [NBu4][2] are readily displaced by Br- to produce [NBu4][3]. The dichloro complexes [NEt4][4] and [PPN][4] are obtained by treating [CpCr(NO)Cl](2) with [NE4]Cl and [PPN]Cl, respectively. Use of acetonitrile as reaction solvent allows generation of the requisite [CpCr(NO)Cl](2) directly from CpCr(NO)(CO)(2) and PCl5, a marked improvement over previous synthetic routes to this dimer. Similar halogenations of Cp*Cr(NO)(CO)(2) in NCMe provide access to the previously unknown [Cp*Cr(NO)I](2) (5), and [Cp*Cr(NO)Cl](2) (6), halo-bridged, and dimers. The solid-state molecular structure of [PPN][4]. CH2Cl2 has been established by single-crystal X-ray crystallography to be a normal three-legged piano stool. The one-electron oxidation of [4] has been investigated both chemically (by reaction with [Cp2Fe](+)) and electrochemically (by cyclic voltammetry). These studies suggest that upon oxidation a high-spin CpCr(NO)Cl-2 complex is initially formed which then rapidly releases NO. Extended Huckel molecular-orbital calculations have been performed on [4], [CpCr(CO)(3)](-), and [CpCrCl3](-), three CpCr-containing anions with ligands of varying pi-bonding capabilities. Correlations between their orbital energies and electron occupancies and a rationale for the lability of the NO ligand in neutral CpCr(NO)Cl-2 are provided.},
