Abstract: 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 Ar 1 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.

Abstract: 1,201,210. 2-(Nitro-phenyl) alkyl halides. BOFORS A.B. 1 Aug., 1968 [4 Aug., 1967], No. 36833/68. Heading C2C. A method of preparing a 2-(nitrophenyl) alkyl halide comprises halogenating a 2-(nitrophenyl) alkanol with a halogenation agent. Specified halogenation agents include thionyl chlorides, phosphorus tri- and pentachloride, cone. hydrochloric acid, hydriodic acid and phosphorus tribromide or triiodide. Examples describe the preparation of 2-(o-nitrophenyl) ethyl chloride using thionyl chloride or concentrated hydrochloric acid, and of 2-(o-nitrophenyl) ethyl bromide using hydrobromic acid.
