cleavage of piperic acid via KMnO4 to piperonal
« on: April 24, 2004, 04:45:00 PM »
If I want to go from Piperic Acid to Piperonal...
How is the cleavage with Potassium Permanganate done?
how are the byproducts removed?
And what yield do i have to expect?
from Rhodium:
via KMnO4
piperic acid --> piperonal
KMnO4, alkali, 3°C
byproducts: piperonylic acid, racem. 2,3-dihydroxy-succinic acid, oxalic acid

Thanks, Elmö
