# Can you synthesize phenol from salicyladehyde?

Can you synthesize phenol from salicyladehyde? Well for starters I know that salicyladehyde can be obtained from phenol through Reimer–Tiemann reaction but I was wondering if the reverse was possible.

• Oxidation and decarboxylation. But this is an expensive way to make phenol. – Lighthart Mar 22 '16 at 19:35
• An even more expensive way: stoichiometric rhodium decarbonylation. Apparently, though, that is now possible catalytically. – SendersReagent Mar 22 '16 at 20:49

It is possible to convert salicylaldehyde into phenol in a two-step process. Firstly, salicylaldehyde is oxidized to salicylic acid with a standard reagent like $\ce{KMnO4}$ (see the answers to this question).
