N-substituents in 5,6-dihydro-2,4-diphenylnaphtho[1,2-b]pyridiniums are transferred to piperidine by unimolecular and / or bimolecular processes in chlorobenzene solution. The kinetics of this reaction at variable temperatures were studied. It has been shown that the reaction follows either SN1 or SN2 mechanisms dependant on the nature of N-substituent.
