Metal-containing compounds Aluminum isopropoxide

The reaction time and concentrations used depend on the reactants. Reaction is usually effected at 60°. Formation of condensation products from the ketones is largely repressed by working in inert solvents such as benzene, dioxan, and toluene. Aluminum isobutoxide, as well as the isopropoxide, has proved its value as metal alkoxide usually it is added to the reaction mixture in the proportion of 0.5 mole per mole of alcohol. Compounds containing nitrogen and halogen can also be oxidized by the Oppenauer method. Dehydrogenation of cholesterol to cholestenone will be described as an example 454...
