A novel synthetic method for the preparation of aliphatic aldehydes from the corresponding carboxylic acids via 1,3-dimethylbenzimidazolium salts is provided. 1,3-Dimethylbenzimidazolium salts were rapidly reduced with sodium/ethanol and then hydrolyzed with hydrochloric acid to obtain aliphatic aldehydes, in which the 1,3-dimethylbenzimidazolium salts can be readily achieved from the corresponding carboxylic acids. The mechanism for the reductive reaction of 1,3-dimethylbenzimidazolium salts with sodium/ethanol was discussed.

3,4-Disubstituted 4-deazatoxoflavin derivatives (II) were prepared by the condensation of 6-(1-methylhydrazino)uracils (I) with appropriate α-diketones.The compounds II oxidized long-chain alkylamines such as n-octylamine and n-dodecylamine besides benzylamine and cyclohexylamine to yield the corresponding carbonyl compounds via imines, catalytically with a markedly high turnover number.
