Etard reaction :Aromatic aldehydes (benzaldehyde and its derivatives) are prepared from aromatic hydrocarbons by Etard .

Stephen reaction : Alkyl nitriles on reduction with stannous chloride and hydrochloric acid in dry ether give corresponding imine hydrochlorides which on acid hydrolysis, give corresponding aldehydes.

Gattermann -koch reaction: Aromatic aldehydes (benzaldehyde and its derivatives) are prepared from aromatic hydrocarbons by Gattermann Koch's.

Rosenmund reduction: is the hydrogenation of an acyl chloride to an aldehyde, in presence of catalyst (Pd supported on barium sulphate). Barium sulphate partially poisons Pd metal and prevents over-reduction
