Bridging and terminal coordination of Ga-Ga bonds by the chelating ligands imidotetraphenyldiphosphinate and -dithiodiphosphinate

Tetrakis[bis(trimethylsilyl)methyl]digallane(4) (1) reacted with imidotetraphenyldiphosphinic acid to yield two products, which were separated by recrystallization: The first one, bis[bis(trimethylsilyl)methyl]-imidotetraphenyldiphosphinato-O,O′-gallium (2), resulted from the cleavage of the Ga-Ga bond and contained a dialkylgallium unit, which was coordinated by a chelating imidodiphosphinato ligand. The digallium compound 1,2-bis[bis(trimethylsilyl)-methyl]-bis(μ-tetraphenyldiphosphinato-O, O′)digallium (3) was formed as the second product by a substituent exchange reaction and the release of bis(trimethylsilyl)methane. Its Ga-Ga bond (245.7 pm) was bridged by two imidodiphosphinato ligands. In contrast, the reaction of digallane(4) 1 with the sulfur derivative imidotetraphenyldithiodiphosphinic acid afforded a complicated mixture of unknown products. A compound analogous to 3 containing two imidodithiodiphosphinato ligands (5) was, however, obtained in a moderate yield by the precipitation of lithium acetate, when we treated dialkyldi(μ-acetato)digallium (4) with lithium imidotetraphenyldithiodiphosphinate. Remarkably, the chelating ligands did not adopt a bridging position across the Ga-Ga bond (249.9 pm) similar to 3, but each one was terminally coordinated to one Ga atom.

Competitive interactions and glassy state extension in lithium salt solutions

We report measurements of high- and low-temperature limits of the liquid states of aqueous solutions for two common aqueous salt solutions. The liquid range extends from the glass transition temperature to the boiling point, and is maximized when the anion basicity is minimized. These limits and other characteristic temperatures have been determined by DTA and DSC studies of solution samples which are used to generate the most complete phase diagram yet available for the LiBr + H2O system. The glass-formation region has been extended by developing an emulsification technique suitable for use with concentrated aqueous salt solutions. Comparison of boiling points, liquidus temperatures, and glass transition temperatures shows that the reduction of the water content below 3H2O per Li+ is accompanied by important energetic effects. These are not present in the corresponding lithium acetate solutions, which exhibit relatively much lower boiling points. This is attributed to the stronger water - anion interaction in the lithium acetate system which is proportional to the anion basicity. Water activity increases and boiling points are lowered when the anions are more basic, but total cohesion, manifested by the glass transition temperature, increases. By contrast, addition of anion complexing salts such as ZnBr2 and ZnCl2 to LiBr-H2O solutions to reduce the anion basicity results in increased boiling points to over 200 ?°C as well as decreased crystallization temperatures. ? 1999 American Chemical Society.

OXIDATIVE EXTRACTION AND ION-EXCHANGE OF LITHIUM IN Li//2MoO//3: SYNTHESIS OF Li//2// minus //xMoO//3 (O less than multiplied by less than equivalent to 2. 0) AND H//2MoO//3** plus .

It is shown that lithium can be oxidatively extracted from Li//2 MoO//3 at room temperature using Br//2 in CHCl//3. The delithiated oxides, Li//2// minus //x MoO//3 (0 less than multiplied by less than equivalent to 1. 5) retain the parent ordered rocksalt structure. Complete removal of lithium from Li//2MoO//3 using Br//2 in CH//3CN results in a poorly crystalline MoO//3 that transforms to the stable structure at 280 degree C. Li//2MoO//3 undergoes topotactic ion-exchange in aqueous H//2SO//4 to yield a new protonated oxide, H//2MoO//3.

A Zinc Catalyzed C(sp3)?C(sp2) Suzuki–Miyaura Cross-Coupling Reaction Mediated by Aryl-Zincates

The Suzuki–Miyaura (SM) reaction is one of the most important methods for C?C bond formation in chemical synthesis. In this communication, we show for the first time that the low toxicity, inexpensive element zinc is able to catalyze SM reactions. The cross-coupling of benzyl bromides with aryl borates is catalyzed by ZnBr2, in a process that is free from added ligand, and is compatible with a range of functionalized benzyl bromides and arylboronic acid pinacol esters. Initial mechanistic investigations indicate that the selective in situ formation of triaryl zincates is crucial to promote selective cross-coupling reactivity, which is facilitated by employing an arylborate of optimal nucleophilicity.

Synthesis, characterization, and catalytic behavior of methoxy- and dimethoxy-substituted pyridinium-type ionic liquids

Synthesis of methoxy-substituted pyridinium-type ionic liquids from a nontoxic and easy method is described. Catalytic behaviors of synthesized ionic liquids were investigated with various concentrations for the Mannich reaction. We have observed that methoxy- and dimethoxy-substituted pyridinium bromides showed better catalytic behavior than other ionic liquids.

N-(2,4,6-trimethylborazinyl)-substituted phosphanes, arsanes, and stibanes

Reaction of the N-lithioborazine LiH2N3B 3Me3·OEt2 (2) in di ethyl ether with PCl3 or PBr3 leads to the borazinylphosphanes (Me 3B3N3H2)PX2, (Me 3B3N3H2)2PX (X = Cl, Br), and (Me3B3N3H2)3P, depending on the initial stoichiometry. The analogous arsane and stibane derivatives were obtained in a similar manner. While (Me3B 3N3H2)2PBr is reduced by LiAlH 4 in diethyl ether/hexane to give the monophosphane (Me 3B3N3H2)2PH (13), the reaction of (Me3B3N3H2)PBr 2 (5) with LiAlH4 in diethyl ether/hexane produces the zwitter-ionic compound [Me3B3N2(HN)] -P+H2Et (14). Dehalogenation of (Me 3B3N3H2)2PBr (6) with Na yields the diphosphane (Me3B3N3H 2)2PP(H2N3B3Me 3)2 (18), while the mixed diphosphane (Me 3B3N3H)2PPmes2 (17) is obtained from 6 and LiPmes2. Dehalogenation of Me3B 3N3H2PBr2 with Na results in the exclusive formation of (Me3B3N3H 2)4P4 (19), while the reaction of 5 with Li2Pmes leads to a mixture of cyclotetraphosphanes (mes) 4-n(Me3B3N3H2) nP4 (A-F) along with bicyclic P4mes 2. The new compounds have been characterized by NMR and IR spectroscopy and partly by mass spectrometry. X-ray structures for compounds, 4, 5, 6, 9, 13, 14, 17, 18, 19, and E have been determined. All show different B-N bond lengths within the borazine rings, and some have borazine rings in a half-chair conformation. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

PROCESS FOR THE RECOVERY OF MATERIALS FROM A DESULFURIZATION REACTION

Disclosed herein is an improved method for regenerating materials from a desulfurization/demetallation reaction. The desulfurization/demetallation reaction preferably has products including one or more of an alkali sulfide, polysulfide or hydrosulfide, or alkali earth sulfide, polysulfide, or hydrosulfide. The method includes the steps of reacting the desulfurization/demetallation products with a halogen, liberating and removing sulfur from the product, and then electrolyzing the halogenated products to separate the halogen from the alkali metal or alkali earth metal.
