Benzaldehyde, a fundamental aromatic aldehyde, is a subject of extensive study due to its rich chemistry and broad synthetic utility. Its reactivity, stemming from the aldehyde functional group and the aromatic ring, makes it a valuable precursor in organic synthesis for a wide range of chemical products.

One of the most characteristic reactions of benzaldehyde is its susceptibility to oxidation. In the presence of air, it can be slowly oxidized to benzoic acid, a process that necessitates the addition of stabilizers like hydroquinone for prolonged storage. This oxidation pathway is a fundamental aspect of its chemical behavior. Conversely, benzaldehyde can be readily reduced to benzyl alcohol, another important industrial chemical. These redox reactions are central to its application as a reactant in numerous synthetic routes.

Benzaldehyde also undergoes characteristic aldehyde reactions. For example, it can participate in condensation reactions, such as the Perkin reaction, where it reacts with acetic anhydride in the presence of sodium acetate to yield cinnamic acid. This reaction is a cornerstone for producing unsaturated aromatic compounds. Another significant reaction is the Cannizzaro reaction, where in the presence of strong alkali, two molecules of benzaldehyde disproportionate, one being oxidized to benzoic acid and the other reduced to benzyl alcohol. Furthermore, its ability to react with amines to form Schiff bases, and with alcohols to form acetals, broadens its synthetic scope.

The phenyl group in benzaldehyde also allows for electrophilic aromatic substitution reactions, typically yielding meta-substituted products, such as m-nitrobenzaldehyde upon nitration. This highlights the influence of the aldehyde group as a deactivating and meta-directing substituent on the benzene ring.
