The 9-mesityl-10-methylacridinium cation in aerated deuterated/normal acetonitrile decomposes to give several side products when continuously exposed to white light. The main breakdown product isolated by column chromatography is identified as 3,5-dimethyl-4-(10-methylacridinium)benzaldehyde. This assignment was confirmed by single-crystal X-ray crystallography. In light of these findings it appears that decomposition pathways also need to be considered when discussing the photochemical properties of the 9-mesityl-10-methylacridinium cation, especially in the presence of dioxygen.
