4-Nitrobenzaldehyde is used in the preparation of homoallylic alcohols. It is also involved in the development and evaluation of a series of tripeptide organocatalysts.
1,3-Oxathiolanes (see 2-Mercaptoethanol, A15890) can be selectively cleaved in the presence of dithioacetals using 4-nitrobenzaldehyde catalyzed by TMS-OTf: J. Chem. Soc., Chem. Commun., 1937 (1994). This combination has been used for conversion of thioketones to ketones: Tetrahedron Lett., 36, 2277 (1995).
