The reaction of 1-methyl-3-nitro- and 1-methyl-3,6-dinitro-4-chloro-2(1H)-quinolinones with 1,2-ethanedithiol leads to 1-methyl-3-nitro- and 1-methyl-3,6-dinitrospirodithiolanes>.The ability of the latter to form anionic Meisenheimer spiro ? complexes is less than in the analogous derivatives of benzopyranone and benzothiopyranone.
