Late last night, not completely sober, I was pondering the possibility of forming the pseudonitrosite of plain styrene, decomposing it and reducing the resulting nitrostyrene to phenyl acetaldehyde and oxidising the latter to phenylacetic acid. This morning I miraculously remembered my musings of the night before. I tried, but couldn't find anything using TFSE, so it's probably a stupid idea. Before I look any further I'd like to know if it really is and, if so, why.
Anybody?

aurelius is just finishing up a styrene to phenylacetic acid with mass-spec analysis to boot. so far, just have the sodium salt of the final product but a GOOD yeild seems to be in order. haven't done any weighings of the salt so yeilds are still up in the air. used the procedure at Rhodium's site

with a couple of variations (very minor) when completely done a write up will be posted.
Over-all, aurelius can say this- stinky, but VERY EASY.
Well, morpholine is out of the question for me and the S + NH4OH thing sounds pretty noxious. So my question, why not pseudonitrosite, remains unanswered.

You think ammonia is more noxious than nitric oxide fumes? Oh man are you in for a surprise.

PP: It is not the ammonia, but the copious quantities of H2S generated in the Willgerodt reaction that is the "problem". I'd choose a pseudonitrosite reaction in my kitchen over a willgerodt in my garage any day of the week.

I wholeheartedly agree.

No, I don't think that and I won't be surprised by any fumes. I'll pass 'm over NaOH solution, which will readily absorb it to form NaNO2 again. Cleans up most noxiousness. Very economic too. :)
