  • Hydrodehalogenation of Halogenated Aryl Ketones under Multiphase Conditions. 5. Chemoselectivity toward Aryl Alcohols over a Pt/C Catalyst
    作者:Maurizio Selva、Pietro Tundo、Alvise Perosa
    DOI:10.1021/jo971957w
    日期:1998.5.1
    Halogenated aryl ketones (XC6H4COR: X = Cl F: R = Me Et, Ph) and benzyl alcohols (XC6H4CH(OH)R: X = Cl; R = Me, Et) have been reduced catalytically over PVC ai 50 degrees C, by bubbling H-2 at atmospheric pressure into a multiphase system consisting of a hydrocarbon solvent (isooctane) and an alkaline aqueous phase (KOH 50%) in the presence of a phase-transfer (PT) agent (onium salts or polyoxyethylene monoalkyl ethers). The chemoselectivity of the reaction is sharply modified by the PT-agent: in its absence, a wide range of products is observed, including those deriving from the complete reduction of both the aromatic ring and carbonyl functions. instead, the presence of the PT-agent allows several different halo ketones to be transformed into their corresponding benzylic alcohols: that is, the hydrodechlorination occurs only with the partial hydrogenation of the CO group to the CH(OH) one, while further reductions are totally prevented. Under such conditions, both ionic (onium salts) and nonionic (polyoxyethylene monoalkyl ethers: Brij 35, 52, 56, and 58) compounds have been tested, and results seem to suggest that the higher their hydrophilicity is, the better the chemoselectivity toward the formation of dehalogenated alcohols is as well. Moreover, under multiphase conditions, also halo aryl alcohols lead to the corresponding dechlorinated alcohols in quantitative yields although a slower reaction is observed with respect to ketones.

  • Synthesis of Substituted Phenyl Ketones via Pd-Catalysed hydrodechlorination of Their Polychlorinated Derivatives
    作者:Andrea Bomben、Carlos A. Marques、Maurizio Selva、Pietro Tundo
    DOI:10.1055/s-1996-4344
    日期:1996.9
    The following compounds, 2- and 3-methylacetophenones, 2- and 3-methylbenzophenones, and 2,2’-, 2,3’- and 3,3’-dimethylbenzophenones have been synthesized through a Pd-catalysed hydrodechlorination of the corresponding dichlorinated derivatives. The reaction has been carried out under multiphase conditions at 30-50°C, by bubbling H2 at atmospheric pressure into a biphasic system constituted by an organic substrate solution (isooctane solvent) and an aqueous alkaline solution (50% aq KOH), in the presence of Pd/C (5% wt) and Aliquat 336 (triaprylylmethylammonium chloride). Likewise, fluorinated aceto- and benzophenones (4-fluoro-3-methylacetophenone and 4-fluoro-3-methylbenzo-, 4-fluoro-2’,3-dimethylbenzo-, 4-fluoro-3,3’-dimethylbenzophenones) have been prepared starting from the corresponding chlorinated methylfluoro- and dimethylfluoro ketones. Under such conditions, the presence of the onium salt allows the reaction to proceed with a high chemoselectivity: chlorine is removed while both the reduction of the carbonyl group and/or fluorine removal are prevented.
