The intramolecular nucleophilic addition of N-methyl-N-(2,4,6-trinitrophenyl)glycine anion in methanol-dimethyl sulfoxide mixtures produces spiro.The spiro adduct has been identified by means of 1H and 13C NMR spectroscopy.This is the first case when the formation of a Meisenheimer adduct with carboxylate ion is observed.Logarithm of the equilibrium constant of adduct formation increases linearly with the mole fraction of dimethyl sulfoxide in its mixture with methanol.
