Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Heterocycles called Photochemical behavior of halogenoheterocyclic derivatives. The alternative between arylation and dehalogenation reactions, Author is D’Auria, Maurizio, which mentions a compound: 2689-65-8, SMILESS is IC1=CC=C(O1)C=O, Molecular C5H3IO2, Formula: C5H3IO2.

Semiempirical calculations on the transient intermediates involved in the irradiation of haloheterocyclic compounds showed that the difference between the heat of formation of the substrates and that of the radical intermediates derived from cleavage of the C-X bond can be a useful parameter to justify the observed chem. behavior towards arylation or dehalogenation.

Formula: C5H3IO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Stereospecific Synthesis of Tri- and Tetrasubstituted α-Fluoroacrylates by Mizoroki-Heck Reaction. Author is Rousee, Kevin; Bouillon, Jean-Philippe; Couve-Bonnaire, Samuel; Pannecoucke, Xavier.

Ligand-free, efficient, palladium-catalyzed Mizoroki-Heck reaction between Me α-fluoroacrylate and arene or hetarene iodides is reported for the first time. The reaction is stereospecific and provides fair to quant. yields of fluoroalkenes. The Mizoroki-Heck reaction starting from more hindered and usually reluctant trisubstituted acrylate, to access tetrasubstituted fluoroalkenes, is also reported. Finally, the use of a three-step synthesis sequence, including Mizoroki-Heck reaction, allows the synthesis of fluorinated analogs of therapeutic agents with high yield.

Gra Rios, Rafael published an article about the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8,SMILESS:IC1=CC=C(O1)C=O ).Related Products of 2689-65-8.

The NMR spectra of a series of 5-substituted furfurals (where the substituent is MeO,Me,Br,I,COOMe,CHO or NO2) were measured in 1% CCl4 solutions The influence of the substituent upon the relation of the cis-trans rotational isomers was studied by means of the correlation between the chem. shifts of the substituted furfurals (referred to furfural) and the resp. shifts of the 5-mono substituted furans (referred to furan). For the H atom in the 4 position, an excellent agreement was found between the substituted furfural and the substituted furan series, whereas for the H atom in the 3 position, there is a noticeable deviation for the iodo compound This could be due to an alteration in the cis-trans isomerism in 5 iodofurfural as compared to furfural, which may be originated in the steric hindrance of I which favors the 0-0 trans isomer and therefore a higher shielding in the H atom in the 3 position.

Computed Properties of C7H13BN2O2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: (1-Isobutyl-1H-pyrazol-5-yl)boronic acid, is researched, Molecular C7H13BN2O2, CAS is 847818-64-8, about Synthesis of pinacol esters of 1-alkyl-1H-pyrazol-5-yl- and 1-alkyl-1H-pyrazol-4-ylboronic acids. Author is Ivachtchenko, Alexandre V.; Kravchenko, Dmitry V.; Zheludeva, Valentina I.; Pershin, Dmitry G..

1-Substituted pyrazolylboronic acids and their pinacol esters were prepared by lithiation-borylation reaction sequence starting from bromopyrazoles. Alkylation of 4-bromo-1H-pyrazole gave 1-alkyl-4-bromo-1H-pyrazoles, which were lithiated at -80° and borylated with B(OMe)3 to give 1-R-1H-pyrazole-4-boronic acids [4a-g, R = Me, Et, Pr, (CH2)2CHMe2, (CH2)2OMe, (CH2)3NMe2, (CH2)2CH(OEt)2]. Lithiation of 4-bromo-1-(2-dimethylaminoethyl)-1H-pyrazole (2h) gave 5-lithio-derivative, which on borylation afforded 1-R1-4-Br-1H-pyrazole-5-boronic acid (8). Boronic acids 4a-g are unstable and were deborylated slowly due to hydrolysis by traces of water; the stability of boryl derivatives can be greatly enhanced by converting to corresponding pinacol boronates (10a-g). Direct lithiation of 1-R2-1H-pyrazoles by BuLi at -20° afforded 5-lithio-derivatives, which were converted to corresponding 1-R2-1H-pyrazole-5-boronic acids [17a-e; R2 = Me, iBu, Pr, (CH2)2CHMe2, (CH2)2CH(OEt)2] and their pinacol boronates (18a-e, same R2). The key step in the described methodol. is the regioselective lithiation of the pyrazole ring. The synthesized pinacolates are stable under prolonged storage and can be used as convenient reagents in organic synthesis.

Matrix-isolation and ab initio studies. Author is Rostkowska, H.; Szczepaniak, K.; Nowak, M. J.; Leszczynski, J.; KuBulat, K.; Person, Willis B..

A study of the IR spectra of thiouracils isolated in low-temperature inert matrixes demonstrated that 2- and 4-thiouracils together with their N1- and N3-methylated derivatives as well as 2,4-dithiouracil exist under these conditions only in the oxothione or dithione tautomeric forms. In contrast, S2- and S4-methylated derivatives exist as a mixture of hydroxy and oxo tautomeric forms under the same conditions. The ratio of concentrations of the oxo and hydroxy tautomers and the free energy differences, were exptl. estimated, from the ratio of the absorbances of the NH and OH stretches. An assignment of the observed IR bands, particularly those related to the C:S stretching vibrations, is proposed on the basis of the comparison of the matrix spectra with those calculated by using ab initio methods (3-21G* basis set).
