Polycyclic aromatic hydrocarbons when treated with iodine monochloride in water solutions of sulfuric acid afford iodo- and chloroderivatives. Biphenyl, fluorene, acenaphthene, 1-nitronaphthalene undergo iodination. Naphthalene furnishes a mixture of iodo- and chloroderivatives, prevailing the latter.

Iodine value of rubber and gutta-percha hydrocarbons As Determined by Iodine Chloride
Industrial & Engineering Chemistry Analytical Edition, 1934Abstract HALOGEN absorption methods employing solutions of bromine, iodine bromide, or iodine chloride are widely used for determining the unsaturation of organic compounds. In the use of these methods the choice of halogen reagent, the amount employed, and the time and temperature for the reaction are all important factors which must be given ...

Metalloporphyrin/Iodine(III)‐Cocatalyzed Oxygenation of Aromatic Hydrocarbons
Advanced Synthesis & Catalysis, 2010AbstractHypervalent iodine species have a pronounced catalytic effect on the metalloporphyrin‐mediated oxygenations of aromatic hydrocarbons. In particular, the oxidation of anthracene to anthraquinone with Oxone readily occurs at room temperature in aqueous acetonitrile in the presence of 5–20 mol% of iodobenzene and 5 mol% of a water‐soluble iron(III)

p-Iodinations in hydrocarbon media: continuous flow reactor application
Tetrahedron Letters, 2011Regiospecific iodination of aryl amines, that is, aryl compounds possessing strong electron donating groups (EDG’s) in the p-position, is described. This procedure features not only the unique use of hydrocarbon media for such substitutions but also the absence of any oxidants aside from iodine itself.

Contact charge—transfer interaction of iodine with saturated hydrocarbons
Spectrochimica Acta Part A: Molecular Spectroscopy, 1982Abstract With the help of the thermodynamic quantities just reported, the spectrophotometric properties of the contact charge-transfer complexes of iodine with saturated hydrocarbon solvents such as cyclohexane, methylcyclohexane and heptane have been calculated from the u.v. spectra of iodine in these solvents.

Electrical conductivity of aromatic hydrocarbon-iodine charge transfer complexes
Journal of Materials Science, 1992The electrical conductivity of the anthracene-iodine charge transfer complex has been thoroughly investigated in the temperature range 288–338 K for samples of different molar ratios of anthracene and iodine (1∶1, 1∶1.5, 1∶2, 1∶2.5, 1∶3, 1∶3.5, 1∶4, 1∶4.5, 1∶5, 1∶5.5 and 1∶6).

Electron Spin Resonance in Complexes of Aromatic Hydrocarbons with Iodine
The Journal of Chemical Physics, 1961Accurate measurements of electron spin concentration in semiconducting molecular complexes of perylene and pyrene with iodine have indicated an exponential temperature dependence in excellent agreement with the activation energy for electronic conduction.

Electronic Conduction in Complexes of Aromatic Hydrocarbons with Iodine
The Journal of Chemical Physics, 1961Molecular complexes of the aromatic hydrocarbons pyrene and perylene with iodine were found to have an electronic conductivity 10 to 12 orders of magnitude higher than that of the constituent compounds. The specific resistivities measured were 75 and 8 ohm-cm, respectively.

Thermodynamic properties of complexes of iodine with polynuclear aromatic hydrocarbons
Journal of Inorganic and Nuclear Chemistry, 1979Abstract A manometric technique was developed to measure the vapor pressures of the iodine complexes of six polynuclear aromatic hydrocarbons. Iodine vapor pressure measurements were made at temperatures of 40–140°C. A supplementary aqueous electrochemical technique was employed to obtain data at lower temperatures.

The amino-functionalization of a range of benzylic and some aliphatic saturated and unsaturated hydrocarbons by reaction with imido-iodinanes (PhI═NSO2Ar) is catalyzed by I2 under operationally simple and mild conditions. The first examples of 1,2-functionalization of unactivated C-H bonds using imido-iodinanes as aminating agents are reported ...
