α,α′-Diamino- p-tetrafluoroquinodimethane: Stability of One- And Two-Electron Oxidized Species and Fixation of Molecular Oxygen

Herein, we report the synthesis, characterization, and reactivity of α,α′-diamino-p-tetrafluoroquinodimethane, a p-tetrafluorophenylene-bridged monosubstituted carbene-based Thiele's hydrocarbon A. The compound exhibits a reversible two-step one-electron oxidation with a marginally stable radical cation state B. The in situ formation of the radical cation could be confirmed by electron paramagnetic resonance spectroscopy. Interestingly, α,α′-diamino-p-tetrafluoroquinodimethane fixates atmospheric oxygen to form a 16-membered peroxide-bridged macrocyclic compound C.

Perfluoroparacyclophane and methods of synthesis and use thereof

A composition comprising perfluoro-[2,2]-paracyclophane dimer compound is disclosed. The synthesis reaction of the paracyclophane dimer from 1,4-bis(chlorodifluoromethane)-2,3,5,6-tetrafluorobenzene involves heating in the presence of a metal catalyst and a solvent. A perfluorinated paraxylylene coating formed from the perfluorinated paracyclophane dimer is also disclosed.
