N,N′-Diphenylpiperidine-1-carbohydrazonamide 1 was prepared and treated with halo compounds, active nitriles, diethylhy malonate, ketones, CS₂, phenylisocyanate, phenylisothiocyanate, LR, ethyl 2-cyano-3,13-dithiomethylacetate, and benzylidenenitriles to give the corresponding triazines 2-4, pyrazoles 5 and 6, triazoles 7, 8, and 10, triazaphosphole 11, and triazepines 12-14, respectively.
