Hey folks. Where could I find a reference that would tell me the experimental pKa values for a range or protonated ethers? For small ones I find things that say "about -3.5" and for phenolic ethers I see ones that say "about -6.5" but I'd like to know the difference between dimethyl and diethyl and anisola and benzylphenyl ether, for example. Is there a spot on the web or a reference book that has all of this tabulated? Thanks for any help you can give.
