The reaction of difluorodioxirane with caesium trifluoromethoxide

Abstract

The reaction of difluorodioxirane with caesium trifluoromethoxide in the presence of CsF forms CF₃OOC(O)F and the new compounds CF₃O(OCF₂O)_nOC(O)F (n = 1≡3); ¹³C labeling shows that the dioxirane undergoes ring opening at the O–O bond.
