'''2-Nitrocinnamaldehyde''', '''''ortho''-nitrocinnamaldehyde''' or '''''o''-nitrocinnamaldehyde''' is an organic ] compound containing a ] ] ortho- to the 1-position of ].

==Synthesis==

2-Nitrocinnamaldehyde can be synthesized by dissolving cinnamaldehyde to a solution of ] in ], and adding a stoichiometric amount of concentrated ] at 0–5&nbsp;°C. Yields are around 36-46% of theoretical.

] of cinnamaldehyde via acidification of a ] salt with ] also yields the ortho-nitro compound, however it also yields some of the para-nitro compound, which is generally undesired.

2-Nitrocinnamaldehyde can also be prepared by reacting ] with ] in a condensation reaction.<ref>{{cite web | url=http://www.orgsyn.org/orgsyn/prep.asp?rxntypeid=181&prep=CV4P0722 | title=Organic Syntheses }}</ref>

==Uses==

2-Nitrocinnamaldehyde can be oxidized to ] which can be used in the ] to produce ] and substituted indoles.
