The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Characteristic group frequencies of bromo- and iodoalkanes in the cesium bromide region》. Authors are Bentley, F. F.; McDevitt, N. T.; Rozek, Adele L..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Quality Control of 1-Iodo-2-methylbutane. Through the article, more information about this compound (cas:616-14-8) is conveyed.
The infrared spectra of 74 normal and branched bromo- and iodoalkanes were recorded and studied, 667-286 cm.-1 The number and position of the frequencies characteristic of the C–X stretching vibration are dependent on the rotational isomers present as well as the structure of the alkyl substituents in the vicinity of the C–X group. Conformational structures and representative spectra are presented along with correlation charts which list the C–X stretching vibration for various primary, secondary, and tertiary bromo- and iodoalkanes.
After consulting a lot of data, we found that this compound(616-14-8)Quality Control of 1-Iodo-2-methylbutane can be used in many types of reactions. And in most cases, this compound has more advantages.
