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.

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.

Vlasov, Vladislav M. published the artcileSubstituent effects in substrates on activation parameters in the bimolecular nucleophilic reactions in solution, Recommanded Product: 4-Iodo-3-nitrobenzonitrile, the publication is New Journal of Chemistry (2010), 34(12), 2962-2970, database is CAplus.

Changes of the activation parameters, ΔH^{â‰?/sup> and ΔSâ‰?/sup>, in the S_N2, S_NAr and acyl-transfer reactions with charged and neutral nucleophiles in various solvents were correlated with σ constants of the substituents in the aromatic ring of the substrates. The resultant δΔHâ‰?/sup> and δΔSâ‰?/sup> reaction constants are linearly related for variations of substituents at the substrate. Correlation of δΔHâ‰?/sup> vs. δΔSâ‰?/sup> allows one to estimate the contribution of changes of the internal enthalpy, δΔHâ‰?/sup>_int, to the enthalpy reaction constant, δΔHâ‰?/sup>, which gives a single linear dependence on the Hammett ρ reaction constants for all bimol. nucleophilic reactions. The deviations from dependence of δΔHâ‰?/sup>_int vs. ρ can be interpreted in terms of changes of the transition state structure or reaction mechanism. The results obtained show that the substituent effects in the substrates and nucleophiles on the charge development in the transition state are governed by the magnitude of δΔHâ‰?/sup>_int.}

The far ir spectra of pyridine-iodine monochloride (I) and pyridine-iodine monobromide (II) complexes have been measured in the region from 500 to 80 cm.-1 in paraffin mulls. Three absorption bands were observed and assigned as I: ν16b (pyridine) = 425, νICl = 265, νNI = 170 cm.-1; II, ν16b(pyridine) = 421, νIBr = 200, and νNI = 160 cm.-1 Under assumptions of a linear triat. model and fNI,ICl = fNI,IBr, the force constants were calculated: fICl = 1.18 (estimated by the Badger rule), fIBr = 1.05, fNI(Cl) = 0.91, fNI(Br) = 0.85, and fNI,ICl = fNI,IBr = 0.22 (millidyne)/A.). The force constant of the interhalogen vibration, fIX, is one half of that of the free mol. The interaction constant is larger than that of a usual mol., which will be characteristic of the mol. complex. 16 references.

Herein a direct vicinal difunctionalization of thiophenes via the palladium/norbornene (Pd/NBE) cooperative catalysis is reported. A series of mono- and disubstituted thiophenes can be difunctionalized site-selectively and regioselectively at the C4 and C5 positions in good yields, enabled by an arsine ligand and a unique amide-based NBE. The synthetic utility has been shown in derivatizations of complex bioactive compounds and an open-flask gram-scale preparation Preliminary results have been obtained in the difunctionalization of furans and a direct C4-selective arylation of 2-substituted thiophenes.
