In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
Via condensations like the Henry reaction, nitroethane converts to several compounds of commercial interest.Condensation with 3,4-dimethoxybenzaldehyde affords the precursor to the antihypertensive drug methyldopa; condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene, a precursor for amphetamine drugs.
In the so-called Ter Meer reaction (1876) named after Edmund ter Meer, [14] the reactant is a 1,1-halonitroalkane: The reaction mechanism is proposed in which in the first slow step a proton is abstracted from nitroalkane 1 to a carbanion 2 followed by protonation to an aci-nitro 3 and finally nucleophilic displacement of chlorine based on an ...
3,4-Methylenedioxypropiophenone, also known as 3,4-(Methylenedioxy)phenyl-1-propanone (MDP1P), is a phenylpropanoid found in some plants of the genus Piper and is an isomer of 3,4-methylenedioxyphenyl-2-propanone (MDP2P).

This category includes chemical compounds that include a phenyl group, C 6 H 5 –. (That is, benzene with only one substituent or bond.) For benzene derivatives ( derivatives or structural analogs of benzene ) in which benzene has multiple substituents or bonds, see the parent category, Category:Benzene derivatives .
1-nitropropane is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane , nitroethane , 1-nitropropane, and 2-nitropropane . 1-nitropropane is also a byproduct of the process for making 2-nitropropane, which is done by vapour phase nitration of propane.
