The complexation reaction between iodine and 1,10-Diaza-18-Crown-6 (DA18C6) has been studied in acetonitrile by spectrophotometric, biamperometric and conductometric techniques. The results are indicative of the formation of [(CH3CH)nI+.I¯3] from iodine and acetonitrile, and the formation of DA18C6 I+. I¯ from DA18C6 and [(CH...

the complex formation reaction between iodine with tetrabutylammonium halides (tbax) has been studied spectrophotometrically in chloroform solution at 25ºc. various aspects of the spectra of iodine in the presence of various concentration of different tetrabutylammonium halides have been discussed in terms of electronic specifications of iodine and halides. in the case of tetrabutylammonium iod...

the regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. the conductivity titration and uv spectroscopy were used to study the interaction of iodine with these catalysts. the results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...

The formation of charge-transfer complexation between dibenzo-15-crown-5 (DB15C5) and benzo-12-crown-4 (B12C4) (Donor) and iodine is investigated spectrophotometrically in three chlorinated solvents,chloroform, dichloromethane (DCM) and 1,2-dichloroethane (DCE) solution at 25°C. The change in polarityof the solvent also doesn’t affect the stoichiometry of the complexes. Values of formation cons...

The sol–gel transition and the mechanical properties of a supramolecular poly(vinyl alcohol)–iodine complex can be tuned in time thanks to an “iodine clock”.

Charge Transfer (CT) complexes formed between dibenzo-24-crown-8 (DB24C8) as an electron donor with the σ-electron acceptor iodine (I2) in chloroform, dichloromethane, and 1,2-dichloroethane solutions have been studied by different spectroscopic techniques at room temperature. The spectral studies of the complexes were det...
