Molecular formula :
nature : aniline acid solution in benzene using phosphorus pentachloride or thionyl chloride processing into chlorinated imine, with stannous chloride reduced imine, which then hydrolysis aldehyde. Aromatic applied to the synthesis of aldehydes. Fatty acid amide not form a stable chloro imine, which can not use this method. Α, β - unsaturated acyl aniline can form a stable chloro imine using chromium chloride-reduction method can be used synthetic α, β - unsaturated aldehyde.
