|Section2= |Section3= }} 2-Nitrocinnamaldehyde, ''ortho''-nitrocinnamaldehyde or ''o''-nitrocinnamaldehyde is an organic aromatic compound containing a nitro group ortho- to the 1-position of cinnamaldehyde. ==Synthesis== 2-Nitrocinnamaldehyde can be synthesized by dissolving cinnamaldehyde to a solution of acetic anhydride in acetic acid, and adding a stoichiometric amount of concentrated nitric acid at 0–5 °C. Yields are around 36-46% of theoretical. Nitration of cinnamaldehyde via acidification of a nitrate salt with H2SO4 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 2-nitrobenzaldehyde with acetaldehyde in a condensation reaction.〔http://www.orgsyn.org/orgsyn/prep.asp?rxntypeid=181&prep=CV4P0722〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2-Nitrocinnamaldehyde」の詳細全文を読む スポンサード リンク
