Photocatalytic cleavage of C-F bond in pentafluorobenzoic acid with titanium dioxide-P25

The photocatalytic C-F bond cleavage in pentafluorobenzoic acid (PFBA) with TiO2-P25 using UV-C light has been investigated under different conditions. Complete cleavage of C-F is observed with TiO2-P25 under UV-C light irradiation.

o-fluoranil chemistry: Diels-Alder versus hetero-Diels-Alder cycloaddition

(Chemical Equation Presented) The title quinone undergoes [4 + 2] cycloadditions in two ways, Diels-Alder on the ring and hetero-Diels-Alder by attack at the oxygens. The latter mode of reaction is strongly favored thermodynamically, but there is a kinetic bias favoring the normal Diels-Alder addition that often prevails, especially with cycloaddends that are not electron-rich.

INTERACTION OF PENTAFLUOROPHENOL WITH LEAD TETRAACETATE IN ACIDS

The ability of polyfluorinated hydroxyaromatic compounds to be oxidised by radical and ionic mechanisms is discussed.Oxidation of pentafluorophenol by lead tetraacetate in hydrogen fluoride and trifluoroacetic acid gave the products of a reaction proceeding by an ionic mechanism - hexafluorocyclohexa-2,5-dienone and trifluoroacetoxydienones respectively.
