The neutral cyclobutanetrione 2 is synthesized from dimeric ketenylidene(triphenyl)phosphorane 1 by treatment with two equivalents of N‐p ‐tolylsulfonyl(phenyl)oxaziridine. Oxidation of 1 with one equivalent of the oxaziridine provides compound 3 , which like 2 was characterized by X‐ray structure analysis. Compound 3 functions as a dienophile in Diels–Alder reactions.
