Not sure if this is a new synth or not but just seen a vid where a guy uses propionate salts+ nitrite in an electrolisys cell yeilding nitroethane. https://m.youtube.com/watch?v=6fqJUpjsXd4Ephraim_Bane - 5-3-2023 at 16:34
This guy has no characterization of his product and claims "it worked." He also asked ChatGPT for a synthesis, which absolutely will not work. ChatGPT
is a chatbot, designed to create plausible-sounding answers, not an actual knowledge base. Despite that, iirc I've seen discussion of a similar route
with proprionate(?) salts and nitrite somewhere.BromicAcid - 5-3-2023 at 17:59
ChatGPT is pretty terrible at complex chemistry but does reasonable at explaining basic concepts. We've been trialing SYNTHIA for a few years now and
it's pretty good to find reliable routes though it's still up to the chemists to apply their skill set figuring out the nuances.
He did mention he had to tweek the procedure to optimise it otherwise it would have yeilded less than a ml. If he actually got 10ml of nitroethane
from 18g prop salt then
you have to admit its a very viable route. Any other nitroethane routes get way less at best for 5x the effort.

Maybe you can try the procedure on a small scale and try verify that the product truly is nitroethane and yields.
Nitroethane is rather hard to get so a viable route is intresting if it works.Texium - 6-3-2023 at 09:59

Don’t have to admit anything when there’s no characterization of the product and the source of the procedure is an AI chatbot.
Might as well piss in a vial and call it nitroethane if that’s the level of evidence you’re willing to accept.clearly_not_atara - 6-3-2023 at 16:41
Claims by early workers in this field to have effected anodic syntheses of alkyl halides and nitroalkanes, by electrolysis of mixtures of
carboxylates and either inorganic halides or nitrites respectively, have not been substantiated in subsequent investigations. Of these attempted
crossing reactions those with salts of fatty acids and sodium nitrate have been studied most thoroughly (for review see ref. 114). A typical
example is the electrolysis of a propionate-nitrate mixture which yields a variety of products including ethyl nitrate, n-butyl nitrate, and the
dinitrates of ethylene glycol and butane-1,4-diol. The formation of derivatives with the same number of carbon atoms as the Kolbe product is
particularly noteworthy.
Sorry, no. But maybe a useful synthesis of 1,4-butanediol? Careful with those alkyl nitrates!

You guide students right?
I really hope you don't grade them like you judge YouTube shit.
