"Abnormal" displacement in the reaction of 2-(N-methylpyrrolyl)methyltrimethylammonium salts with sodium cyanide. Carson, John R.; Hortenstine, John T.; Maryanoff, Bruce E.; Molinari, Albert J. (Chem. Res. Dep., McNeil Lab., Inc., Fort Washington, Pa., USA). J. Org. Chem., 42(6), 1096-8 (English) 1977. CODEN: JOCEAH.There are some commonly used reagents with their cas registry numbers 24437-41-0 and 54828-80-7 in this article. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Treatment of title compds. I (X = Cl) with NaCN in refluxing H2O-xylene gave Me3N, 9:1 II-III, and some IV via V (X = Cl) ion pair intermediate. The cyanolysis of I (X = iodo, MeSO4, p-MeC6H4SO3, CF3SO3) was also examd. The II-III ratio depended on X. .
