withdrawal and give rise to the iminium derivatives 15 - 17. These salts as well as the corresponding enamines show, after addition of D2O, exchange phenomena in the NMR spectra, which indicate an equilibrium in each case. The Hg(II)-EDTA dehydrogenation in the homologous piperidine series gives the corresponding results. From the anabasine derivative 18 the lactam 19 is produced, and from 2-benzyl-1-methylpiperidine
