The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Analysis of rotatory dispersions of configurationally related halides》. Authors are Levene, P. A.; Rothen, Alexandre; Marker, R. E..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Computed Properties of C5H11I. Through the article, more information about this compound (cas:616-14-8) is conveyed.

Rotatory dispersion curves of halides of the type HMeRC(CH2)nX (X = Cl, Br, I; R = alkyl group; n = 0, 1, 2 or 3) are analyzed in the visible and the ultraviolet regions. The 3 halogen atoms function similarly with respect to the character of this curve in compounds of identical structure. A periodicity in the sign of some of the partial contributions of the halogen atom occurs with increase in n. The course of the rotatory dispersion when n = 1 is anomalous. An attempt is made to apply results when n > 0 to the sign of rotation for compounds where n = 0. When X = COOH, CHO, CN, CHMe2, etc., no complete analogy exists between this group and the group where X is a halogen. [M]D25 maximum (homogeneous) is given for the 16 compounds where X = Br, n = 1, 2, 3, 4, and R = Et, Pr, Bu, pentyl, and for the compound HMeEtC(CH2)5Br. Absorption spectra are given for λ 2100-3300 for 5 iodides. Rotatory dispersion curves are given for the compounds HMeEtCCH2I, HMe(C6H13)CCH2I, HMeEtCCH2Br and HMeEtCCH2Cl. [M]D25 maximum, nD25, d425 (vacuum) and rotatory dispersions (numerical) are given for several other compounds in this series. Differences between the interpretation of the dispersions of the iodides given by the authors (C. A. 27, 951) and that given by Kuhn (C. A. 29, 7159.1) are due to substantial differences between their exptl. data.

Category: thiomorpholine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms.

Influence of structure on retention time and sensitivity to electron capture detector. Author is Castello, Gianrico; D’Amato, Giuseppina.

The retention times and indexes observed for 34 alkyl iodides during electron-capture gas-liquid chromatog. on a 15% tricresyl phosphate/Chromosorb W (DMCS-treated)column are examined as functions of the number of C atoms, the I position, and the number and position of branchings in the alkyl iodide mols. The relative molar response of the electron-capture detector is useful for detector standardizations since it depends only on the standing current.
