Shiels, Oisin J.;Kelly, P. D.;Bright, Cameron C.;Poad, Berwyck L. J.;Blanksby, Stephen J.;da Silva, Gabriel;Trevitt, Adam J. research published 《 Reactivity Trends in the Gas-Phase Addition of Acetylene to the N-Protonated Aryl Radical Cations of Pyridine, Aniline, and Benzonitrile》, the research content is summarized as follows. A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N-containing aromatics In cold diffuse environments, such as the interstellar medium, rates of radical addition may be enhanced when the σ-type radical is charged. This paper investigates the gas-phase ion-mol. reactions of acetylene with nine aromatic distonic σ-type radical cations derived from pyridinium (Pyr), anilinium (Anl), and benzonitrilium (Bzn) ions. Three isomers are studied in each case (radical sites at the ortho, meta, and para positions). Using a room temperature ion trap, second-order rate coefficients, product branching ratios, and reaction efficiencies are measured. The rate coefficients increase from para to ortho positions. The second-order rate coefficients can be sorted into three groups: low, between 1 and 3 x 10-12 cm3 mol.-1 s-1 (3Anl and 4Anl); intermediate, between 5 and 15 x 10-12 cm3 mol.-1 s-1 (2Bzn, 3Bzn, and 4Bzn); and high, between 8 and 31 x 10-11 cm3 mol.-1 s-1 (2Anl, 2Pyr, 3Pyr, and 4Pyr); and 2Anl is the only radical cation with a rate coefficient distinctly different from its isomers. Quantum chem. calculations, using M06-2X-D3(0)/6-31++G(2df,p) geometries and DSD-PBEP86-NL/aug-cc-pVQZ energies, are deployed to rationalize reactivity trends based on the stability of prereactive complexes. The G3X-K method guides the assignment of product ions following adduct formation. The rate coefficient trend can be rationalized by a simple model based on the prereactive complex forward barrier height.
626-01-7, 3-Iodoaniline is a useful research compound. Its molecular formula is C6H6IN and its molecular weight is 219.02 g/mol. The purity is usually 95%.
3-Iodoaniline is a fatty acid that is used in analytical methods to measure the concentration of human serum in blood. It can be used to estimate the population growth rate, with a half-life of about 13 hours. 3-Iodoaniline reacts with hydrogen bond and proton to form a reaction solution, which can be catalyzed by palladium-catalyzed coupling and suzuki coupling reactions. The activation energies for these reactions are typically in the range of 4-8 kcal/mol. The chemical ionization technique is a type of mass spectrometry that is used to determine kinetic data for this compound. Hydrochloric acid can be added as an acid catalyst to increase the rate of reaction and generate more accurate kinetic data., SDS of cas: 626-01-7
