Trifluoromethyl peroxy

Bcnzaldehydes with fluoro substituents (monofluoro, trifluoromethyl) on the aromatic ring are readily oxidized to peroxy compounds 1 with 30% hydrogen peroxide, while the oxidation with concentrated hydrogen peroxide leads to geminal hydroxy hydroperoxides 2.185... 

Peroxy esters are a known class of compounds. Fluorinated peroxy esters can be prepared208,209 by the reaction of the hydroperoxides with fluorinated acyl chlorides or acid anhydrides in the presence of pyridine as the base. It has also been demonstrated210 that trifluoromethyl... 

Bis(fluoroxy)difluoromethane reacts with carbonyl difluoride over CsF to yield a bis(trifluoromethyl) trioxide, CF3OOOCF3, bp -19°C, or the peroxy acyl fluoride, CF300C(0)F, depending on conditions (equation 55). At low temperature, the trioxide is favored. 

The final section of this Section of the Report is associated with the derivatives of trifluoromethyl hydroperoxide. The new compounds CF3OOPOF2 and CF3OPOF2 have been prepared by the reaction of trifluoromethyl hydroperoxide CF3OOH with iU-oxo-bis(phosphoryl difluoride), P2O3F4, and difluorophosphine-iw-oxo-phosphoryl difluoride, P2O4F4. The i.r. and n.m.r. spectra, physical properties, and some chemical reactions are reported for the new compounds. New synthetic routes to bis(trifluoro-methyl)bis(peroxy)carbonate (CF300>2C0 and trifluoromethyl fluoroformyl peroxide CF300C(0)F, based on the catalytic disproportionation of bis-(fluoroformyl) peroxide FC(0)00C(0)F, have also been derived. ...
