Electrochemical Reduction of Organic Compounds. 22. Preparation of Aromatic Aldehydes by Electroreduction of Esters and Amides in the Presence of Chlorotrimethylsilane
The electroreduction of aromatic esters 1 and amides 9 in dry acetonitrile in the presence of chlorotrimethylsilane 2 affords aldehydes 3 in moderate to good yields depending on the aromatic substituents. The formation of 3 and characteristic by‐products is discussed.
