Is it possible to eliminate the Para Hydroxy Group from 4-Hydroxyphenylacetone(CAS.770-39-8) with H2SO4 to afford Phenylacetone?
I'd expect a lot of side reactions (aldol especially).
Also, the target compound is illegal in the US--I don't know where you're operating though. 😉
So maybe a selective dehydration would be the solution? Im currently in a Country where this Compound is not illegal, just for clarification!
