1,205,168. Diaryl ketones. BOFORS A.B. 23 July, 1968 [4 Aug., 1967], No. 35175/68. Heading C2C. 1,2-Diaryl ketones of formula in which Ar and ArSP1/SP are unsubstituted or substituted phenyl groups are prepared by oxidizing a 1,2-diaryl ethan of formula with nitric acid in the presence of a substantially inert organic solvent which is substantially immiscible with the nitric acid. Suitable solvents are halogenated hydrocarbons, e.g. chloroform. An example is given of the oxidation of 1-phenyl-2-(o-nitrophenyl) ethanol to o-nitrodesoxy benzoin.
