Transetherification tolerance
« on: January 20, 2014, 05:03:32 AM »
Hi,
I have a question about the tolerance of the pTSA catalyzed transetherification reaction with an alcohol in toluene at 90°C.
Just a quick example. For instance, I have a methoxy bearing styrene (like 4-methoxystyrene), can I do a transetherification on the methoxy group using (butan-1-ol , pTSA, toluene) ? Will the vinyl group take part in the reaction?
Thank you!

Trans etherification will not work under these conditions. You are more likely to get addition to the double bond.
Development Chemists do it on Scale, Research Chemists just do it!

4-methoxystyrene contains no ester moiety whatsoever.  Please read about what esters are and their transformations.

If you're not part of the solution, then you're part of the precipitate

Yeah my bad.  I read esterification that whole time. 

I was wrong.
