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).Application In Synthesis 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.
There are many compounds similar to this compound(616-14-8)Application In Synthesis of 1-Iodo-2-methylbutane. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
