Chaikovskii, V. K. published the artcileIodination of aromatic compounds with iodine monochloride in aqueous sulfuric acid, Application In Synthesis of 2100-25-6, the main research area is iodination aromatic compound iodine chloride; toluene iodination iodine chloride; chemoselectivity iodination aromatic compound iodine chloride; regioselectivity iodination aromatic compound iodine chloride; alkylbenzene iodination iodine chloride; durene iodination iodine chloride; anisole iodination iodine chloride; aniline iodination iodine chloride.

Iodine monochloride in aqueous sulfuric acid turned out to be a convenient and general reagent for preparative iodination of alkylbenzenes, phenol ethers, and aromatic amines. The relative selectivity and activity of iodine monochloride in aqueous solutions of sulfuric acid with various concentrations were determined using toluene as model substrate. Raising the sulfuric acid concentration results in considerable increase of the electrophilicity of ICI. Effective sulfuric acid concentrations were determined for specific substrate series. Iodine monochloride in aqueous sulfuric acid shows enhanced selectivity in the synthesis of monoiodo derivatives

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.

A wide range of aromatic compounds (e.g., C6H6) have been effectively iodinated with a pyridine-iodine monochloride complex (I). Condensed polycyclic iodides, which are not readily obtained via direct iodination, can be prepared indirectly via their corresponding organomercurials in 1 step. Some benzoid and nonbenzoid heterocycles (e.g., indole) are iodinated with I.

The spent reagents after the synthetic reactions were easily removed by filtration and were regenerated for further use. The efficiency of these reagents towards mono-selectivity in aromatic iodination and the variation of reactivity of the iodinating reagents as a function of the nature of solvent, effective molar concentration and temperature were investigated.

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.

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.

Maya, Francisco published the artcileSynthesis of Fluorinated Oligomers toward Physical Vapor Deposition Molecular Electronics Candidates, Safety of 4-Iodo-3-nitroaniline, the main research area is fluorinated oligomer thiol nitrile pyridine chemisorption gold platinum; safety deprotection thioacetate.

New electron-deficient fluorinated oligo(phenylene ethynylenes) (OPEs) with varied functional groups were synthesized as free thiols, nitriles, and pyridines, ready to be used for surface adhesion. Calculated dipole moments suggest better matching between energy levels of bulk interfaces and mol. frontier orbitals when compared to nonfluorinated OPEs. Differential scanning calorimetry confirmed a higher thermal stability than the nonfluorinated counterparts. Surface anal. by ellipsometry, contact angle goniometry, cyclic voltammetry, and surface IR and XPS verified that the OPEs chemisorb on Au and Pt surfaces. On the basis of the phys. properties of the fluorinated OPEs, they might be useful in future phys. vapor deposition techniques, methods that are typically used in standard semiconductor fabrication processes. Safety: deprotection of a thioacetate derivative led to a violent explosion.
