Zingaro, Ralph A. published the artcileInfrared studies of amine-halogen interactions, Application In Synthesis of 6443-90-9, the publication is Journal of Physical Chemistry (1960), 1705-11, database is CAplus.

The marked changes which are brought about in the 1000-cm.^-1 region of the infrared spectrum of pyridine on the addition of I are generally characteristic of amine-halogen solutions Infrared studies on a series of solutions of amines and halogens revealed corresponding infrared shifts. Several new solid amine-halogen complexes were isolated, and, in every case, the frequency shifts in solution were correlated with infrared bands characteristic of the solids.

Khansole, Sandeep V. published the artcileKinetics of iodination of aniline and substituted anilines by pyridinium iodochloride in methanol, Recommanded Product: Pyridine Iodochloride complex, the publication is Physical Chemistry: An Indian Journal (2007), 2(3), 167-170, database is CAplus.

The kinetics of iodination of the aniline and substituted anilines using pyridinium iodochloride in methanol has been studied under varying conditions. The rates shows first order kinetics each in pyridinium iodochloride and anilines. The rates of reactions are measured at different temperature and activation parameters for all amines computed. Hammett plot is found to be valid and the correlation between the enthalpies and free energies of activations is reasonably linear with an isokinetic temperature 347 K. Similarly log A values of all the amines are optimized corresponding to Ea of amines through the equation, log A = logk_obs + Ea/2.303RT.

Lightfoot, Andrew P. published the artcileOn the mechanism and origin of the stereoselectivity in iodo-deboronation and chloro-deboronation of hindered alkenyl boronate esters using either ICl-NaOMe or ICl-pyridine, Product Details of C5H5ClIN, the publication is Tetrahedron Letters (2004), 45(46), 8557-8561, database is CAplus.

Conversion of hindered alkenyl boronate esters into the corresponding iodoalkene, or alkenyl chloride can be carried out stereoselectively using ICl. In the presence of NaOMe, direct reaction of ICl is favored yielding the E-iodoalkene, however, the reaction with ICl followed by NaOMe can be used to give different major alkenyl iodide and chloride products, depending upon reaction temperature, ICl source and alkenyl boronate stereoelectronics.

By oxidative-addition reactions of X₂ (X = Br, I) and XI.py (X = Cl, Br) to SnCl₂ in the presence of pyridine, SnCl₂X₂py₂ (X = Br, I), SnCl₃Ipy₂ and SnCl₂BrIpy₂ were obtained and studied by vibrational and ¹¹⁹Sn Moessbauer spectroscopy. A C_2v symmetry, with the ligands in trans positions, was proposed for SnCl₂Br₂py₂, whereas Moessbauer spectra of the remaining species show the presence of some impurities. A linear regression between the position of some pyridine bands in the IR spectra and the average electronegativity of halogens was observed, the υ₄ frequency being the most sensitive with respect to the metal-ligand bond strength.

Zingaro, Ralph A. published the artcileInfrared spectra of pyridine coördinated iodine(I) salts, Recommanded Product: Pyridine Iodochloride complex, the publication is Journal of the American Chemical Society (1959), 1353-7, database is CAplus.

The spectra of (Ipy)X (py = C₅H₅N and X = OAc, BzO, CN, F, Cl, Br, ClO₄, and NO₃), (Ipy₂)ClO₄ and NO₃, and (pyH)I are determined and compared with those of py and solutions of I₂ in py. The results are related to data from studies of ultraviolet spectra and conductivities of I₂-py solutions The py-I₂ complex must be very polar. On the basis of the spectral change resulting from coördination of py with I₂ it is suggested that the 990-cm.^-1 band of py be assigned to a H deformation mode. (Ipy)CN is prepared by adding I₂ to AgCN suspended in a CHCl₃ solution of py. AgI and AgCN are separated and the filtrate evaporated at 1 mm. Hg and Dry-Ice temperature The compound forms orange crystals which can be kept as long as 10 days in vacuo at Dry-Ice temperature Decomposition begins at 34° and is rapid at 50-3°. It is colored only in nonpolar solvents. (Ipy)F is prepared similarly from AgF. It forms pale yellow crystals which decompose over the range 80-97°. It is soluble in EtOH and Me₂O with subsequent decomposition It is insoluble in CCl₄, CHCl₃, or CS₂. Decomposition is instantaneous on contact with water.

Sheinker, V. N. published the artcileStudy of the structure and properties of heterocyclic compounds and their complexes. XXXIII. Charge transfer complexes of bromine iodide and chlorine iodide with azoles, Name: Pyridine Iodochloride complex, the publication is Zhurnal Obshchei Khimii (1976), 46(11), 2576-9, database is CAplus.

UV and dipole moment data were given for complexes of imidazoles, pyrazoles, thiazoles, oxazoles, and isoxazoles with ClI and BrI. The stability of the BrI complexes was lower than that of the ClI complexes, but both types were more stable than the analogous I2 complexes. The change of the dipole moment on complexation, the degree of charge transfer, and the stability constant all increased as the basicity of the azole increased.

A series of mol. adducts, L-ICl, where L = pyridine or a pyridine derivative, were prepared and the solid state spectra examined by Raman and far-IR spectroscopy. Assignments of the modes ν(I-Cl) 240-300 cm^-1 and ν(N-I) 90-180 cm^-1 and force constant calculations in a simple 3-center model yield information on structure and bonding related to the nature of the pyridine donor. Several ionic products containing the ICl₂^– ion were encountered.

The anal. of spin-lattice relaxation in NQR (NQR) of spin-(5/2) reported by Okubo and Igarashi (Z. Naturforsch. A. 56 (2001) 777) is extended to take account of the distribution of the initial non-equilibrium populations created by a resonant radio-frequency pulse in powder. The proposed theory is applicable to axially sym. elec. field gradient tensor and is examined for spin-lattice relaxation of ¹²⁷I NQR in polycrystalline pyridine iodine monochloride measured at 469 MHz at 77 K.
