Title: Piperonal...which way to go?
Post by: onevegasdave on February 20, 2004, 11:35:00 PM

If some newbee were practicing and whipping up a batch of piperonal with Vanillin, can 4-Hydroxy-3-methoxybenzaldehyde (C8H8O3)be used with the same expected results as 3,4,5-trimethoxybenzaldehyde (C10H12O4)?

Any help would be greatly appreciated

Hest...what i mean to say is if a rxn calls for Vanillin, can 4-Hydroxy-3-methoxybenzaldehyde(C8H8O3)be used interchangebly with 3,4,5-trimethoxybenzaldehyde (C10H12O4)?

Title: Making piperonal from vanillin is not the same
Post by: sYnThOmAtIc on February 22, 2004, 03:31:00 AM

Making piperonal from vanillin is not the same as making 3,4,5 TMB from vanillin one is a demethylation and the other is a methylation. Vanillin must be demethylated first to give 3,4 dihydroxybenzaldehyde before piperoanl can be made from it.

What thet hell does 4-Hydroxy-3-methoxybenzaldehyde(C8H8O3)be used interchangebly with 3,4,5-trimethoxybenzaldehyde (C10H12O4)? mean?
 If you explain what your trying to do maybe someone coudl help you.
