The spectroscopy of InSe nanoparticles
Yang, Shuming,Kelley, David F.
, p. 12701 - 12709 (2005)
The synthesis of several different sizes of InSe nanoparticles from organometallic precursors is reported. These particles are characterized by transmission electron microscopy, electron diffraction, and optical spectroscopy. The electron diffraction results and optical properties indicate that these particles are two-dimensional disks, consisting of single Se-In-In-Se tetralayer sheets. The absorption spectra indicate strong quantum confinement along the z axis and, for the smaller particles, in the x,y plane. The z-axis quantum confinement may be quantitatively understood in terms of the band structure of bulk InSe. The results indicate that the z-axis quantum confinement reverses the order of the direct and indirect transitions in the case of the largest particles. The smaller particles exhibit strong, polarized fluorescence, and the fluorescence polarization may also be understood in terms of the band structure of bulk InSe. ? 2005 American Chemical Society.

The structures of trimethylindium (Me3In) adducts with the bidentate tertiary amine N,N,N′,N′-tetramethyl-4,4′-methylenebis(aniline)[MBDA] and the macrocyclic amines 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane [N4-aza crown] and 1,4,7,10,13,16-hexamethyl-1,4,7,10,13,16-hexaazacyclooctadecane [N6-aza crown] have been determined by single crystal X-ray diffraction. The adducts have the following stoichiometries, Me3In·2MBDA 1, 2Me3In·MBDA 2, 4Me3In·N4-aza crown 3 and 6Me3In·N6-aza crown 4. Compound 1 contains five-coordinate Me3In in a trigonal bipyramidal configuration and displays the longest In-N bond lengths yet reported (2.720(4), 2.865 A); 2-4 contain four-coordinate Me3In molecules in a tetrahedral configuration. Compounds 1-4 can be used as intermediate adducts in the adduct purification of Me3In for use in the MOVPE (metal organic vapour phase epitaxy) of InP and related III-V semiconductors.

Paragraph 0126-0129, (2020/05/30)
The invention relates to a method for producing alkyl metal compounds, starting materials for the production of trialkyl gallium and trialkyl indium comprise metallic indium or metallic gallium, at least one alkyl donor, a reducing agent and a solvent; the alkyl donor is alkyl halide; R in MR 2-4 represents alkyl group, 2 to 4 R groups are independently selected from the same or different alkyl groups; M is especially aluminum, gallium or indium; high purity gallium or indium or aluminum is used; sesquialkyl aluminum chloride is used as a reaction promoter, and the metal gallium or metal indium is reacted with alkyl chloride of the alkyl donor at low temperature and low pressure to generate sesquialkyl gallium chloride or sesquialkyl indium chloride; when the sesquialkyl gallium chloride or indium sesquialkyl chloride is reduced to the trialkyl gallium or trialkyl indium by a reducing agent, metal gallium or metal indium is necessarily generated simultaneously; the newly generated metal gallium or metal indium reacts with chloromethane (ethyl) in situ, so that the starting materials are fully utilized. The yield of the two steps is almost complete. The new synthetic route is an environment-friendly green process.
A phosphine-free, heterogeneous palladium-catalyzed atom-efficient carbonylative cross-coupling of triorganoindiums with aryl halides leading to unsymmetrical ketones

, p. 13862 - 13870 (2017/11/27)
The first phosphine-free heterogeneous palladium-catalyzed carbonylative cross-coupling of aryl halides with triorganoindiums has been developed that proceeds smoothly under 1 or 2.5 atm of carbon monoxide in THF at 68 °C and provides a general and powerful tool for the synthesis of various valuable unsymmetrical ketones with high atom-economy, good yield, and recyclability of the catalyst. Our system not only avoids the use of phosphine ligands, but also solves the basic problem of palladium catalyst recovery and reuse.
Aryl-NHC-group 13 trimethyl complexes: structural, stability and bonding insights
Wu, Melissa M.,Gill, Arran M.,Yunpeng, Lu,Yongxin, Li,Ganguly, Rakesh,Falivene, Laura,García, Felipe
, p. 854 - 864 (2017/01/29)
Treatment of aromatic N-substituted N-heterocyclic carbenes (NHCs) with trimethyl-gallium and -indium yielded the new Lewis acid-base adducts, IMes·GaMe3 (1), SIMes·GaMe3 (2), IPr·GaMe3 (3), SIPr·GaMe3 (4), IMes·InMe3 (5), SIMes·InMe3 (6), IPr·InMe3 (7), and SIPr·InMe3 (8), with all complexes being identified by X-ray diffraction, IR, and multinuclear NMR analyses. Complex stability was found to be largely dependent on the nature of the constituent NHC ligands. Percent buried volume (%VBur) and topographic steric map analyses were employed to quantify and elucidate the observed trends. Additionally, a detailed bond snapping energy (BSE) decomposition analysis focusing on both steric and orbital interactions of the M-NHC bond (M = Al, Ga and In) has been performed.
Transition-Metal-Free Cross-Coupling of Indium Organometallics with Chromene and Isochroman Acetals Mediated by BF3·OEt2
Gil-Negrete, José M.,Sestelo, José Pérez,Sarandeses, Luis A.
, p. 4316 - 4319 (2016/10/12)
A transition-metal-free coupling of triorganoindium reagents with benzopyranyl acetals mediated by a Lewis acid has been developed. The reaction of R3In with chromene and isochroman acetals in the presence of BF3·OEt2 afforded 2-substituted chromenes and 1-substituted isochromans, respectively, in good yields. The reactions proceed with a variety of triorganoindium reagents (aryl, heteroaryl, alkynyl, alkenyl, alkyl) using only 50 mol % of the organometallic, thus demonstrating the efficiency of these species. Preliminary mechanistic studies indicate the formation of an oxocarbenium ion intermediate in the presence of the Lewis acid.

We report the continuation of a focused medicinal chemistry program aimed to further optimize a series of imidazo[1,2-a]pyrazines as a novel class of potent and selective phosphodiesterase 10A (PDE10A) inhibitors. In vitro and in vivo pharmacokinetic and pharmacodynamic evaluation allowed the selection of compound 25a for its assessment in preclinical models of psychosis. The evolution of our medicinal chemistry program, structure-activity relationship (SAR) analysis, as well as a detailed pharmacological profile for optimized lead 25a are described.

supporting information, p. 608 - 611 (2015/03/05)
A modular and completely stereoselective approach for the construction of all-carbon tetrasubstituted alkenes is described. It is based on the three-fold, sequential metal-catalyzed, cross-coupling functionalization of simple enolphosphate dibromide templates with carbon nucleophiles, affording tetrasubstituted alkenes as single isomers.
