Title: Decarboxylation of 2-hydroxy-4-acrylic benzoic acid
Post by: Rafeekee1337 on May 15, 2007, 04:23:55 PM

I was wondering if any one knew a way to decarboxylate 2-hydroxy-4-acrylic benzoic acid.  I was wondering if Br2/HgO, CCl4, heat would do the trick to get put a bromine where the acid was. Then take Mg/ether to make a grignard to remove with H3O+. I think the Br2 will react with the acrylic group andbu im not sure and im not sure if it will do anything to the hydroxy group that H3O+ cant fix. I also thought of maybe oxidizing the OH group to a carboxyl group to protect it but then im not sure if i can get the benzene ring back. If anyone has any ideas or set me in the right direction that would be awsome!

thx The Baboon
