摘要
5H-Dibenzo[a, d]cyclohepten-5-ol 2 and its saturated analogue 4 undergo Ritter reactions with acetonitrile and sulfuric acid to afford the acetamide derivatives 3 or 5 respectively. Both products form unstable inclusion compounds when crystallised from dioxane. The crystal structure of the dioxane compound of 3 is reported, This material [(C17H15NO).(C4H8O2)(2), Pnma, a = 9.616(1), b = 23.280(2), c = 10.298(1) Angstrom, Z = 4, R = 0.054] has the amide molecules arranged in parallel chains by means of intermolecular -N-H...O=C hydrogen bonds. The inclusion compound is stabilised by means of -C-H...O- hydrogen bonds. Each dioxane molecule is involved in five such interactions to neighbouring molecules of 3 and dioxane.
