Tossidis, Ioannis A. published the artcileMonohalobenzoylhydrazones. I. Preparation, properties, UV and IR spectra of new monohalobenzoylhydrazones of 2-furaldehyde, 2-thiophenaldehyde, 2-pyrrolaldehyde and di-2-pyridyl ketone, Category: iodides-buliding-blocks, the publication is Chimika Chronika (1983), 12(4), 181-97, database is CAplus.

Aroylhydrazones I (X = F, Cl, Br, iodo, Z = Q-Q³) were prepared from XC₆H₄CONHNH₂ and Z:O and their UV and IR spectra determined and discussed. A halogen atom at C-2 of the benzene ring causes a violet shift of the main UV bands of the spectra and a shift to higher frequencies of the valence swinging of the C:O group in the IR spectra.

Singh, Rajeev Kumar published the artcileApproaches to synthesis of asycyanine colourants and their characterisation, Related Products of iodides-buliding-blocks, the publication is International Journal of Chemical Sciences (2007), 5(3), 1229-1235, database is CAplus.

The number of asycyanine colorants (ACC) are synthesized by the catalytic condensation of auxochromic chalcones such as 4-dimethylaminostyryl 4-nitrophenyl ketone and 4-dimethylaminostyryl 4-methoxyphenyl ketone with different electron rich quaternized azo-heteroaromatics These ACC were obtained with a view to assess their electronic absorptivity. The ACC were found to absorb at longer wavelengths and to show uniform bathochromic shifts compared with the unsubstituted colorants and β-substituted styrylogues. The wavelengths of ACC were in good agreement that weighing at 6-substitution in the heterocyclic systems affect as follows: I > Br > Cl > H and OEt > OMe > Me > H.

Sheka, I. A. published the artcileThe dielectric properties of the iodine halide complexes with some organic compounds, Synthetic Route of 6443-90-9, the publication is Zhurnal Fizicheskoi Khimii (1956), 109-16, database is CAplus.

The dielec. properties of ICl systems with dioxane, pyridine, and quinoline, and of IBr with dioxane, CHCl₃, and CCl₄ as solvents were investigated. The maximum deviations of the dielec. constants and polarization from the calculated values corresponds to the formation of definite complex compounds in solution In the ICl-C₅H₅N and ICl-quinoline systems in CHCl₃, solution, the maximum deviations of ΔAP and Δε are very sharp, and their values exceed by many times the deviations in the systems of IBr and ICl with dioxane and CCl₄. A comparison of the values of the polarization deviations and the instability constants of C₄H₈O₂.ICl and C₄H₈O₂. IBr shows that the systems formed in ICI and IBr by dioxane must be considered irrational, while ICl forms with pyridine and quinoline rational systems. With ICl quinoline forms 2 compounds: C₉H₇N.ICl and C₉H₇N.2ICl; the second is more stable in CHCl₄ solution than is the analogous compound with pyridine.

Sheka, I. A. published the artcileThe application of dielectric polarization for the determination of the composition of complex compounds in solutions, SDS of cas: 6443-90-9, the publication is Izvest. Sektora Platiny i Drug, Blagorod. Metal., Akad. Nauk S.S.S.R., Inst. Obshcheǐ i Neorg. Khim. (1951), 189-202, database is CAplus.

It has been known for some time that the dielec. polarization P for complexes is more than the simple sum of the compounding mols. By comparing numerous reliable data from the literature, it was noted that not only ΔP will accept a rather large value for the case of complex formation, but Δε also, which is understandable, as ε (dielec. constant) appears in the formula for P. By plotting curves ΔP vs. composition and Δε vs. composition, a maximum in such curves will indicate the formation of a complex. For allyl isothiocyanate and piperidine in benzene these 2 maximum coincided with those for viscosity, deviation of the sp. volume, heat of mixing, n, and the temperature coefficient of the viscosity. For pyridine and ICl in CHCl₃ the ΔP and Δε maximum coincided with one of the m.p. maximum in the m.p. diagram of pyridine ICl. Thus the plotting of the ΔP-composition and Δε-composition diagrams may serve to replace other very tedious determinations of other physicochem. values which have been used heretofore to find out the presence or absence of complexes. The maximum in these curves will not occur if merely van der Waals forces are acting. If more than one complex is formed, only one will give rise to a maximum; the other will be indicated by a break in the curve. Thus for the case AlBr₃-dioxane the break is found for (AlBr₃)₂.C₄H₈O₂, whereas the maximum lies at AlBr₃.C₄H₈O₂. The higher the maximum in these curves, the more stable the complexes.

Chem. substances (20) were tested for inhibition of growth of Clostridium perfringens types C and D. Spore suspensions containing a billion cells/cc. were used as test objects. Sterile cloth (0.5 cm. × 0.5 cm.) was soaked in the resp. spore suspension, dried, exposed to 3 cc. of solution and tested for viability. All solutions containing Cl demonstrated a bactericidal action, increasing with temperature The most effective are: acidified bleaching powder and monochloroiodine compounds Acids and alkali solutions are ineffective at low temperature, but strongly inhibitory at 60°. The bactericidal effect of the following substances is enhanced by a combined treatment at different temperatures: solutions of bleaching powder, acidified bleaching powder, monochloroiodines, pyridine iodochlorideHCl, and of OH with etherane 138 (a crude-oil product). The spores of C. Perfringens type D are more resistant than those of type C.

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.
