Treatment of 2,2,2-trifluoro-1-phenylethanone (1) and α,α,α-trifluorotoluene (3) with ozone or ozonized air in chlorinated hydrocarbons in the presence of excess nitrogen dioxide and a catalytic amount of iron(III) salt at -10-0°C leads to the respective title nitro compounds 2 and 4 in good to excellent yields. The reaction is clean and rapid, little or no hydrolysis of the trifluoromethyl group being observed during the nitration.

We present an alcohol oxidation strategy to access α-trifluoromethyl ketones (TFMKs) merging catalytic oxoammonium cation oxidation with visible-light photoredox catalysis. This work uses 4-acetamido-(2,2,6,6-tetramethyl-piperidin-1-yl)oxyl as an organic oxidant capable of generating TFMKs in good yields. The methodology serves as an improvement over previous reports of an analogous oxidation strategy requiring superstoichiometric quantities of oxidant. Both primary and secondary non-fluorinated alcohols can also be oxidised in good yields.
