Formate Ester NMR

Bob Mathews  Follow
Alpha,

What scale did you do the reaction on? Was 13C crude or clean? Citronellal should be cheap, yes?

FYI, Hans Reich is rarely wrong about NMR.

Yes, very cheap.

Have a ton of it.  Only doing it on like 10 grams now for trial reactions.

I have decided it is not the formate from Bayer-Villager.  There is no C13 shift at like 60-70 for the C-O.

Ethyl formate has a shift of about 161 ppm for the carbonyl carbon, which is about the same as methyl formate.  Your shift is within a few ppm of protonated methyl formate, but that seems unlikely.
