How would you synthesize propanoic acid from acetic acid? Give all reagents and intermediates.
I would run a grignard type reaction, since they seem to run very well. Make a grignard reagent out of the acetic acid by first reducing the ...
To the grignard, react with CO2 gas in ether, followed by work up with an acid, say HCl and you will have your propionic acid. See solution for full answer.
