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.
