Activated Alkyl and Cycloalkyl Halides

100 ml EtOAc/1.5 g (18 mmol) NaOAc 20°C, 1 atm H2, 1 h Bubbled into the reaction mixture. 

Selective dechlorination of a-chlorooximes over palladium catalyst was also achieved in an acidic medium.218 2-Chlorocyclohexanone oxime as sulfate or in the presence of 1 equivalent of sulfuric acid was hydrogenated over 10% Pd-C in acetic acid to give 84.5% of cyclohexanone oxime.2180 

The a-fluoro atom activated by a nitro group in polyfluoro compounds such as 84 and 85 was removed on hydrogenation to the hydroxyimio compounds over a palladium black in methanol.221
