Sulfonyl nitrene
A sulfonyl nitrene is a chemical compound with generic formula RSO2N. Known sulfonyl nitrenes include methyl sulfonyl nitrene, trifluoromethyl sulfonyl nitrene, and tolyl sulfonyl nitrene.[1] Also fluorosulfonyl nitrene FSO2N exists, but rearranges to FNSO2.[2] Preparation of sulfonyl nitrenes can be accomplished by heating sulfonyl azides:[3]
- RSO2N3 → RSO2N + N2
They are distinct from sulfinyl nitrenes which only have one oxygen attached to the sulfur atom.
