I am synthesizing a phenyl ether from an alkyl resorcinol and primary alcohol, however my mentor has suggested a 2-step method that I don't fully understand. I was hoping someone could help me understand the purpose of all the reactants so that I can establish a mechanism before actually trying the reaction.

 

I understand the first step of the reaction. It involves activating a primary alcohol by reacting it with sulfonyl chloride. I already have the mechanism, method, and isolation confidently written out. happy.png

 

For the second step, my mentor has suggested taking the alkyl resorcinol and treating it with sodium hydride in a polar aprotic solvent before adding the tosylated alcohol from the first step.

 

Embarrassingly, I cannot say for sure what treating the resorcinol with sodium hydride is supposed to accomplish before addition of the tosylated enolate (Ph-O-+Na?). Can someone please explain to me what this would do? Something that would be even more helpful is if you have a copy of, or link to, a paper in which a similar reaction is carried out.

 

I really appreciate your time! Thank you for any help you can give.

Well you are correct. You generate the phenoxide anion which is more nucleophillic than the phenol. Thus is should react much much faster with the tosylate.
