Description
Silver o-ethylphosphonate was prepared by the reaction of diethylphosphonate with silver nitrate for 8 h in acetonitrile below 10°C. This compound decomposed in alcoholic potassium hydroxide to form silver(II) oxide and ethylphosphonate in the intermediate. When no reducing reagent existed, silver(II) oxide was reduced by ethylphosphonate to deposite silver, which formed a silver film on the glass base. When a reducing reagent existed, it was oxidized by silver(II) oxide. Benzaldehyde and its derivatives with an electron-withdrawing substituent were oxidized to convert corresponding carboxylic acid in a yield of over 90%. This oxidoreduction occurred at room temperature, and finished within 10 minutes. The oxidation reaction of benzaldehyde by silver o-ethylphosphonate could be utilized for the removal of benzaldehyde contained in a liquid aromatic compound. Benzaldehyde <2 v/v% contained in toluene could be removed in a single oxidation reaction, and of 20 v/v% in the operation performed four times.<br>
