Ooooh, now I see it, the two escaped me. The aldehyde is comparatively reactive and readily participates in aldol condensations. Oxidation of toluene to benzaldehyde is quite a useful conversion. Wikipedia gives a different mechanism for the same reaction. Reactuon, benzaldehyde is instrumental in the synthesis of phentermine.
