The Synthesis of Some Highly Strained Pyrylium and N-Benzylpyridinium Salts and Kinetics of their Reactions with Piperidine

5,8-Dimethyl-1-tetralone (11) yields the hindered pyrylium salts (12)-(14), which give the corresponding pyridines and pyridinium salts with ammonia and amines.Chroman-4-one affords the oxoniaphenanthrene perchlorate (17).The additional steric hindrance f

Kinetics and Mechanisms of Nucleophilic Displacements with Heterocycles as Leaving Groups. 2. N-Benzylpyridinium Cations: Rate Variation with Steric Effects in the Leaving Group

N-Benzyl groups are transferred to piperidine from pyridinium ions by unimolecular SN1 and/or bimolecular SN2 mechanisms.Steric acceleration by α-phenyl groups is reduced by an adjacent β-methyl group but increased by constraining th
