secondary alcohol (I) and a satd. ketone (II) uses activated alumina as exchange catalyst. Temp. is 150-300 degrees C and pressure is autogenous. Reaction is performed with a 3-1 molar excess of (I). (I) is and (II) is (chloracetophenone), where R and R1 are alkyl or phenyl ...
Secondaryalcoholsare easilyoxidizedto ketones (R2CHOH → R2CO). The reaction can be halted at the ketone stage because ketones are generally resistant to further oxidation. Oxidation of a secondaryalcoholto a ketone can be accomplished by many oxidizing agents, most often chromic acid (H2CrO4),...

It consists more precisely in a process for oxidizing hydrocarbon, alcohol and/or ketone, using oxygen or a gas containing it, in liquid phase and in the presence of a catalyst dissolved in the reaction medium, characterized in that the catalyst comprises a soluble manganese compound and at ...
Low yields and unpredictableregioselectivityare common in the palladium-catalyzedalkylationof allylic alcohol derivatives with ketone enolates.cis-3-(2-Oxopropyl)-5-phenylcyclohexene is obtained from the reaction ofcis-3-acetoxy-5-phenylcyclohexene with the lithium enolate of acetone, bis(dibenzylideneacet...
PURPOSE:To retain high selectivity, improve the conversion and space time yield and obtain a ketone, by dehydrogenating a secondary alcohol in the presence of a Raney nickel catalyst under specific reaction conditions. CONSTITUTION:A secondary alcohol, preferably secondary butanol is dehydrogenated in...
