Electron-impact studies XCII–Negative ion-molecule reactions in anhydride systems. Perfluoroacetic anhydride with succinic,maleic and phthalic anhydrides. An ion cyclotron resonance study

The trifluoroacetate anion undergoes reaction with succinic, maleic and phthalic anhydrides to yield 1 : 1 adducts. The molecular anions of maleic and phthalic anhydride also undergo reaction with perfluoroacetic anhydride to produce [CF₃CO₂]^?· Maleic anhydride parent ions produce [M + CF₃CO·]^? ions when allowed to react with perfluoroacetic anhydride.
