Acetophenonyl pyridinium salts are versatile reagents in organic reactions, but the reactivities of their carbonyls were seldomly studied. It was found that the reactions of the carbonyls with alcohols occurred when acetophenonyl pyridinium salts were treated with alcohols (or phenol) in the presence of a base giving rise to benzoates, and the departure of pyridyl with the α-carbon atom was involved. High yields (80%～98%) were achieved when they reacted with alcohols, however a yield of 48% were obtained when phenol was used instead of alcohols.
Key words： acetophenonyl pyridinium salt; alcohol; derivative of benzoate
