Enammonium salt of 2-methyl-1-(β-methylstyryl)piperidine (<B>1</B>) was isolated for the first time and characterized. The enammonium salt, 2-methyl-1-(β-methylstyryl)piperidinium chloride (<B>2</B>), was found to change easily to the corresponding iminium salt, 2-methyl-1-(2-phenylpropylidene)piperidinium chloride (<B>3</B>), at room temperature. The structure of the salts derived from 1-(β-methylstyryl)piperidine (<B>4</B>), 2-methyl-1-(β-methyl-styryl)pyrrolidine (<B>5</B>), 1-(β-methylstyryl)pyrrolidine (<B>6</B>), 1-(2-methyl-1-propenyl)pyrrolidine (<B>7</B>), and 2-methyl-1-(2-methyl-1-propenyl)piperidine (<B>8</B>) were also examined.
