Abstract
In a method for deoxygenating the secondary and/or tertiary OH group(s) in an alcohol having such OH group(s), a characteristic feature thereof is that the alcohol having the OH group(s) is first converted into a substituted or unsubstituted benzoate derivative, and the benzoate derivative is then subjected to a photocatalytic reaction in the presence of an electron donor or to an electrode reaction in the presence of an electrolyte, whereby the desired compound in which the OH group(s) has (have) been selectively deoxygenated can be obtained in a high yield on an industrial scale.
Claims9
A method for deoxygenation of an alcohol, wherein said alcohol has a secondary OH group, a tertiary OH group or both a secondary OH group and a tertiary OH group, by selectively deoxygenating said OH groups, which comprises subjecting the alcohol, whose OH groups to be deoxygenated have been esterified with substituted or unsubstituted benzoic acid, to a photocatalytic reaction in a hydrous or anhydrous hydrogen-donating solvent in the presence of an electron donor, said electron donor serving as a catalyst in the photocatalytic reaction which is not consumed during the reaction, or to an electrode reaction in the presence of an electrolyte for deoxygenation.
