An ionic liquid, acetylmethylimidazolium halide ([AcMIm]X), in combination with ceric ammonium nitrate promotes halogenations of a wide variety of ketones and 1,3-keto esters at the ?-position. The ionic liquid acts here as reagent as well as reaction medium, and thus the reaction does not require any organic solvent or conventional halogenating agent. The reaction is completely arrested when the radical quencher TEMPO is used. A plausible radical mechanism is also suggested. CSIRO 2007.

Chlorination of a variety of aliphatic, alicyclic, and aromatic ketones with a reagent combination of NaC1O2 and Mn(acac)3 catalyst can be readily performed in dichloromethane to afford α-chloroketones in good yield under mild and neutral conditions with the aid of chromatographic neutral alumina.
[4 + 3] cycloadditions of cyclic oxyallyls and cyclic 1,3-dienes

The [4 + 3] cycloaddition of the oxyallyl intermediates, derived from 2-chlorocyclohexanone and related compounds, to cyclic 1,3-dienes under the F?hlisch conditions (Et3N in CF3CH2OH) has been examined to assess its scope
Metal-Catalyzed Organic Photoreactions. The Photooxidation of Vinylsilanes and Vinyl Sulfides in the Presence of Iron(III) Chloride, and the Regioselective Synthesis of α-Chloro Ketones
Sato, Tadashi,Tonegawa, Tamotsu,Naoi, Kunio,Murayama, Eigoro
, p. 285 - 286 (2007/10/02)
The irradiation of a pyridine solution of vinylsilanes or vinyl sulfides in the presence of iron(III) chloride under oxygen produced α-chloro ketones, with a carbonyl group at the olefinic carbon originally bearing a silicon or sulfur atom.
