The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Walden inversion. XIII. The influence of substituting groups on optical rotation in the series of disubstituted acetic acids》. Authors are Levene, P. A.; Mikeska, L. A..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).HPLC of Formula: 616-14-8. Through the article, more information about this compound (cas:616-14-8) is conveyed.

cf. C. A. 22, 1953. The conclusion that in the aliphatic series the carbinols and the structurally related halides rotate in opposite directions is substantiated by the study of a series of aliphatic substances derived from disubstituted acetic acids or their corresponding carbinols. Primary halides rotate in the opposite direction to the primary alcs. from which they were derived, while in passing from the corresponding thio to the sulfo derivative the change in rotation is in the same direction, though without change of sign. A decided uniformity was found in the effect on optical rotation of various substitutions of the CO2H group or of the alc. group of the corresponding carbinols, depending upon the position of the subsituting group in the polarity series, C = N > CO2Et > CO2H > CONH2 > COCl > CH2SO3H > CH2X > CH2SH > CH2OH > CH2NH2. The order in this series corresponds with the order of the same groups in polarity series determined by other methods. This relationship holds only for aliphatic substances containing only 1 asym. C atom and only 1 polar group. Active primary amyl alc. was halogenated without marked racemization, while in the rest of the series conversion to the halide from the carbinol by SOCl2, PCl5, HBr, HI, etc., as well as from the amine by NOCl2, led to complete racemization.
