Sulfones are converted into their *nitro derivatives vita displacement by sulfone-stabilized carbanions on alkyl nitrates. The a-nitro sulfones are readily converted into the corresponding cmitro-a-halo sulfones by sequential treatment with base and halogen or by treatment with N-halosuccinimides. Conversion of cmitroebromobutyl butyl sulfone with potassium amide in liquid ammonia into an octenesulfonamide constitutes a novel extension of the Ramberg-Backlund reaction.

The peroxymonosulfate-acetone system produces dimethyldioxirane under conditions permitting distillation of the dioxirane from the synthesis vessel. The same conditions were used to prepare other methyldioxiranes. Solutions of dimethyldioxirane prepared in this manner were used to study its chemical and spectroscopic properties. The caroate-acetone system was also used to study the chemistry of in situ generated dimethyldioxirane.
