%X In methanol solution, 1,4,7-tri(pent-4&#8242;-yn-1&#8242;-yl)-1,4,7-triazacyclononane undergoes an intramolecular hydro-amination reaction to form an azoniaspiro&#91;4.8&#93;tridecane cation, 1-methylidene-8,11-di(pent-4&#8242;-yn-1&#8242;-yl)-8,11-diaza-5-azoniaspiro&#91;4.8&#93;tridecane. The azoniaspiro&#91;4.8&#93;tridecane cation, as its tetraphenylborate salt, has been characterized spectroscopically in solution and by X-ray studies in the solid state. Reactions of the azoniaspiro&#91;4.8&#93;tridecane that lead to other products are also discussed.
