Appropriate 2-ethoxycarbonylpyridinium salts are hydrolysed to 1-aryl-4,6-diphenylpyridinium-2-carboxylate betaines which undergo thermal decarboxylation to afford, in the presence of acids, 1-aryl-2,4-diphenylpyridinium salts.The intermediate ylides are
Deethoxycarbonylation of 2-(Ethoxycarbonyl)pyridinium Salts with Primary Amines and Competing SNANRORC Reactions
Katritzky, Alan R.,Awartani, Radi,Patel, Ranjan C.
, p. 498 - 502 (2007/10/02)
2-(Ethoxycarbonyl)pyridinium salts with primary amines undergo competing SNANRORC and deethoxycarbonylation reactions.Proportions vary: methylamine gives only the former but tert-butylamine only the latter reaction. α-Unsubstituted pyridiniums
