Dimethyl(2-picryloxyethyl)-and dimethyl(3-picryloxypropyl)amines do not form zwitterionic spirocyclic 2,4,6-trinitrocyclohexadienide (Meisenheimer) adducts but undergo intramolecular alkylation to give, respectively, tetramethylpiperazinium and dimethylazetidinium picrates. Likewise, spirocyclic trinitrocyclohexadienide complex with a 4-morpholiniomethyl-1,3-dioxolane ring is regioselectively converted into 2-hydroxy-7-oxa-4-azoniaspiro[3.5]nonane picrate whose structure was proved by X-ray analysis.
