nitroalkanes | Bookmark | |||||
While searching nitroethane in the US patent literature I found these patents which look interesting. 4319059 XCH3COOH + NaNO2 --Mg++--> CH3NO2 4431842 ROH + HNO3 --CaCl2--> RNO2 4073798 MDA related compounds (amines and nitro compounds) made from benzaldehydes and nitroalkanes 4015011 Benzaldehyde and nitroalkane synth, Pd reduction, Eph and halo-Eph compounds reduced 4004023 MD-PNPs insecticidal http://www.geocities.com/dritte123/PSPF. |

US4319059 is cool shit. So, obtaining the nitroethane, nitropropane, etc. from the reaction mixture is as easy as crashing it out with dH2O? ![]() I'm going to help all of you cleanse this diseased planet. |

Re: nitroalkanes | Bookmark | |||||
I saw a post by Rhodium before on this type of reaction. Alpha-haloalkanoic acids generally aren't OTC, but don't seem to be watched either. Also, lactic acid might be easily converted into its alpha-halo form. The possibilities...... If you're interested in nitroethane. http://www.geocities.com/dritte123/PSPF. |

Re: nitroalkanes | Bookmark | |||||
Yes, right! I didn't think of lactic acid as a precursor, but as you say, it is a good alternative. There is also the reaction (in Org. Syn. f ex) which produces alpha-bromo derivatives of carboxylic acids using PBr3, either as is, or using red P + bromine. |

Re: nitroalkanes | Bookmark | |||||
I don't have any references on lactic acid or anything on alpha-halo acids. You might try here. http://www.orgsyn.org/orgsyn/orgsyn/full This looks interesting, too. http://www.orgsyn.org/orgsyn/prep.asp?pr http://www.orgsyn.org/prep.asp?prep=cv4p http://www.geocities.com/dritte123/PSPF. |
