The Diels-Alderreactions of tris(trifluoromethyl)trifluoroacetyl-cyclopropene with dienes gave syn-adducts mainly, due to the electronic effects of the fluorinated substituents.
Reaction of trist(trifluoromethyl)cyclopropenyl trifluoromethyl ketone with azo compounds in the presence of triphenylphosphine, and synthesis of tetrakis(trifluoromethyl)pyridazine.
The title cyclopropenylketone reacts with azo compounds and tri-phenylphosphine to give unique heterocycles; tricyclourazoles and a diazaoxacyclooctatriene. The formers were converted into a pyridazine.
