From J.of Analytical Toxicology vol.6 p.71-75 (1986).By A.T.Shulgin et al., A soln. of piperonal 15 g. in 80 ml. acetic acid was treated with 15 ml. nitroethane and 7 g. anhydrous ammonium acetate, and heated at 100 degrees for 4 hrs. The addition of a few ml. water followed by cooling yielded 8.0 g. 1-(3,4-methylenedioxyphenyl)-2-nitroprop Chemical supply houses sell inacurate chemicals in place of this compound. |

> A soln. of piperonal in 80 ml. acetic acid How much piperonal? I'm not fat just horizontally disproportionate. |

Yield doesn't look that thrilling. | Bookmark | |||||
Yield doesn't look that thrilling. Chemical supply houses sell inacurate chemicals in place of this compound. Huh? which chemical, piperonal or ketone? They wouldn't sell either to me anyway ![]() The above post is purely fictional. Any resemblance to "real-life" is purely coincidental. |

Piperonal & Piperonyl | Bookmark | |||||
Osmium: 15g Piperonal, apparently, even if the above poster doesn't express himself so clearly. This synthesis is very similar to the one in Pihkal #100 for the same nitrostyrene, with the exception of the latter one using cyclohexylamine for a yield of 10.7g, instead of this with NH4OAc, yielding 9g. Carboxyl: The Shulgin article above discusses the ambiguity of the name "piperonylacetone", which can both mean the three-carbon side-chain compound MDP2P and the four-carbon side-chain homolog (the benzylacetone). This is also discussed in Pihkal, see the extensions and commentary part in http://www.erowid.org/library/books_onli |

Thanks for the clarification, it makes sense now. ![]() The above post is purely fictional. Any resemblance to "real-life" is purely coincidental. |
