In the reaction of the glycol ethers of picric acid, containing 2-4 methylene units, with alkali-metal methoxides, tert-butoxides, and glycolates the intermolecular 1,1-?-complexes are formed in addition to the intamolecular spirocyclic anionic ? complexes.Thus, irrespective of the nature of the solvent and the nucleophilic agent, 1-(β-hydroxyethoxy)-2,4,6-trinitrobenzene undergoes intramolecular spirocyclization to a ? complex with a 1,3-dioxolane spirocycle.For 1-(δ-hydroxybutoxy)-2,4,6-trinitrobenzene only the formation of intermolecular 1-methoxy-1-hydroxyalkoxy- and 1,1-dihydroxyalkoxy-2,4,6-trinitrocyclohexa-2,5-dienides is observed, whereas 1-(γ-hydroxypropoxy)-2,4,6-trinitrobenzene can give ? complexes of both types, depending on the polarity of the solvent.
