• 9H-Thioxanthene
• Sulfone
• 2,3-Dibromophthalzine-1,4-dione
• Spirolactone

The reaction of diphenyl sulfone with 2,3-dibromophthalazine-1,4-dione in the presence of n-butyllithium gave a spiro-9H-thioxanthene-10,10-dioxide derivative in 45% yield, the structure of which was proved by X-ray crystallography.
