Catalysis of the beta-elimination of HF from isomeric 2-fluoroethylpyridines and 1-methyl-2-fluoroethylpyridinium salts. Proton-activating factors and methyl-activating factors as a mechanistic test to distinguish between concerted E2 and E1cb irreversible mechanisms

Research has been conducted on beta-elimination reactions. The mechanism of the base-induced beta-elimination reactions in pyridine ring activated systems with fluorine as a leaving group is described.
