Jin, Zuxi published the artcileSynthesis and properties of novel phenylethynyl-containing organodisulfide as cathode material for secondary lithium batteries, Formula: C10H13I, the main research area is synthesis property phenylethynyl containing organodisulfide cathode secondary lithium battery.

A novel phenylethynyl-containing conjugative organodisulfide compound 9-trimethylsilane-ethynyl-5,8-dihydro-lH,4H-2,3,6,7-tetrathia-anthracene (TMSEDTTA) was synthesized by a facile preparation method, characterized by elemental anal., FTIR spectroscopy (FTIR), Raman spectrum, XPS, and TGA, and was tested as cathode active material in rechargeable Li batteries. The electrochem. properties of S-S bonds redox behavior in the organodisulfides were studied in 1.0 M LiClO4/EC/DMC (1:1, volume/volume) solution The system has many advantages, such as high theor. charge d. (∼365 mAh g-1), fast redox process and enhanced reversibility. The fast redox process and enhanced reversibility are due to the intramol. cleavage-recombination of the S-S bond, and the intramol. electrocatalytic effect of phenylethynyl chain. The cyclic voltammogram of TMSEDTTA shows multiple redox peaks. The separation of the anodic and cathodic peak potentials for disulfide bond in TMSEDTTA is 0.4 V. The charge-discharge tests show an initial capacity of 330 mAh g-1 and the coulomb efficiency of >80% after the electrochem. activation.

Kanosue, Kenta published the artcilePolyimides with Heavy Halogens Exhibiting Room-Temperature Phosphorescence with Very Large Stokes Shifts, SDS of cas: 2100-25-6, the main research area is polyimide heavy halogen exhibiting room temperature phosphorescence Stokes shift.

Semiarom. polyimides (PIs) and imide compounds containing heavy halogens (Br, I) in pyromellitic moieties were designed and synthesized to examine their photoluminescence properties. Solutions of imides and PI films exhibited reddish-color room-temperature phosphorescence (RTP) with very large Stokes shifts (ca. 10000 cm-1). In addition, the PI films showed small-Stokes-shifted fluorescence emissions at around 540 nm with absorption bands arising from aggregated PI chains at 400-500 nm. Enhanced phosphorescence observed for the PI films under vacuum indicates that the RTP lifetime is significantly influenced by the triplet-triplet energy transfer to atm. oxygen. These PIs with very-large-Stokes-shifted RTP are applicable as spectral conversion materials in displays, photovoltaic devices, and crop cultivators, as well as to oxygen/air sensors.

Sohmiya, Hajime published the artcileSolid-state organic reactions proceeding by pulverization of inorganic solid-supports. Reactions of iodosobenzene with unsaturated hydrocarbons on acid-treated silica gel, Application of 3-Iodo-1,2,4,5-tetramethylbenzene, the main research area is hydrocarbon unsaturated halogenation oxidation solid state; solid state organic reaction; iodosobenzene reaction alkene acid silica gel; silica gel hydrohalogenated reaction alkene iodosobenzene.

Pulverization of solid mixtures of hydrogen halide-treated silica gels, PhIO, and alkenes or an alkyne in the absence of a solvent causes smooth and rapid reaction to give halogenated or oxidized products in good yields. Thus, treating trans-PhCH:CHPh with HCl-treated silica gel and PhIO in the solid state gives meso- and dl-PhCCl:CClPh in 65% overall yield.

Suzuki, Hitomi published the artcileThe reaction of polysubstituted aromatics. LVI. The copper(I) iodide-assisted reaction of nonactivated aryl iodides with some alkali metal pseudohalides, Formula: C10H13I, the main research area is aryl iodide substitution pseudohalide; azide substitution polymethylaryl iodide; selenocyanate substitution polymethylaryl iodide; tellurocyanate reaction polymethylaryl iodide; cyanide reaction polymethylaryl iodide; cyanide aryl.

CuI dissolves in warm (O)P(NMe2)3 to give a black solution in which polymethylated iodobenzenes undergo nucleophilic attack by azide and selenocyanate ions, giving the corresponding aryl azides and selenocyanates in low to good yields. In the absence of Cu(I) salt, however, the reaction does not take place. Cyanide, cyanate, thiocyanate, and fluoride ions cause a decoloration of the reaction mixture and no displacement reactions ensue, while the tellurocyanate ion gives the corresponding aryl cyanides while liberating elemental Te.

Obeid, Naim M. published the artcile(Oligo)aromatic species with one or two conjugated Si:Si bonds: near-IR emission of anthracenyl-bridged tetrasiladiene, Product Details of C10H13I, the main research area is disilene preparation crystal structure DFT calculation fluorescence; tetrasiladiene paraarylene bridged preparation crystal structure DFT calculation fluorescence; crystal structure disilene paraarylene bridged tetrasiladiene; mol structure disilene paraarylene bridged tetrasiladiene.

Aryl disilenes Tip2Si:Si(Tip)Ar (2a-d) and para-arylene bridged tetrasiladienes, Tip2Si:Si(Tip)-LU-Si(Tip):SiTip2 (3a-d) were synthesized by the transfer of the Tip2Si:SiTip unit to aryl halides and dihalides by nucleophilic disilenides Tip2Si:SiTipLi (Tip = 2,4,6-iPr3C6H2, Ar = aryl substituent, LU = para-arylene linking unit). The scope of the nucleophilic Si:Si transfer reaction is demonstrated to also include substrates of considerable steric bulk such as mesityl or duryl halides Ar-X (Ar = Mes = 2,4,6-Me3C6H2; Ar = Dur = 2,3,5,6-Me4C6H, X = Br or I). Bridged tetrasiladienes Tip2Si:Si(Tip)-LU-Si(Tip):SiTip2 with more extended linking units surprisingly exhibit fluorescence at room temperature, albeit weak. DFT calculations suggest that partial charge transfer character of the excited state is a possible explanation.

Galli, Carlo published the artcileAromatic iodination: evidence of reaction intermediate and of the σ-complex character of the transition state, Related Products of iodides-buliding-blocks, the main research area is aromatic iodination mechanism reaction intermediate; transition state aromatic iodination.

The reactivity of four different procedures of aromatic iodination is compared under the same exptl. conditions, and their selectivity toward two substrates in competition, i.e., mesitylene (I) and durene (II), is evaluated. Two of these procedures, namely, S2O82-/I2 and CeIV/I2, present strong oxidizing capacity. Since the same I/II relative reactivity is obtained from the four procedures, it becomes possible to state that a common reactive intermediate, most likely the I+ ion, is generated. The use of the I/II mechanistic probe suggests the following description of the iodination reaction: electrophilic substitution at the aromatic nucleus, with a transition state properly represented in terms of a σ-complex. The radical cation of II also forms when the iodination is carried out by means of oxidizing agents, but it is solely responsible for the formation of side-chain substitution products and is not involved in the nuclear substitution process.
