Piperonal from 3-4OH Bzaldehyde? | Bookmark | |||||
I don't find any process to synthetize piperonal from 3-4 dihydroxybenzaldehyde. Is it possible to do like the first step of this synth with benzaldehyde insteed benzene? [url=../rhodium /sa ... crazy synth for sweet dreams ... |

3,4-dihydroxybenzaldehyde is also known as protocatechualdehyde. Methylenation reactions can be found in ../rhodium /methyle |

Thanks ! But now the problem is that I don't own an autoclave. Is it possible to replace CH2Cl2 by CH2BR2(b.p. 97°)and reflux the whole instead heat under presure? ... crazy synth for sweet dreams ... |

Yes, dibromomethane or diiodomethane may be used instead. In the link I posted there are a PTC reaction which does not use an autoclave too. |
