Não, será um caminho diferente. Acetoxi somente com ácido peracético.
Síntese de fenilacetona (P2P) a partir de benzaldeído com butanona

Vou tentar essa síntese com dicloro-metano (DCM). Não vejo isso como um problema, apenas o fato de ser mais pesado que a água. Há algum motivo para não usar o DCM e o clorofórmio sintético prontamente disponíveis?
Can 3-methyl-4-phenyl-3-buten-2-one be distilled without vacuum?
- By waltjr5858
Lol it turned to some bad stuff without vac... I went on to the next step the next time with some minor cleaning and no distillation....I didn't clean up till the end with steam distillation... works fine... yield still plenty good enough. I hate the way that stuff vac distilled......

Yup so it wasn't just me... thought I screwed something up but it's pretty easy at that point HA. I've now gotten through the entire thing and just doing a steam distillation at the end and it turns out perfectly every time. Although it took some tries to get there.
Too much GAA use maybe 1.6lish
Hydrolysis is too long in my exp
1.25eq base and 2hrs worked best for me
you didnt get 50% peroxide and attempt this
will d scale up no testing time again
Purification via methylphenylbutanones bisulfite adduct is so much superior (same with p2p) both for not having to make chloroforms sake and end purity
huge excess of mek? Intentional? also amino acids r a better cat than hcl for the aldol and id use perborate for the villiger as thats higher yielding in my exp than H2O2. Percarbonate is less good getting maybe 35% but much easier and not watched at all
