So you are looking to synthesise methyl vinyl ketone?
…
But if you want to make it it is made by and aldol reaction of acetone with formaldehyde followed by dehydration.
No, it's made by a Mannich reaction. It is an org syn prep, look it up.
Well I searched Org. Syn. for Mannich reaction got 14 hits none involved prep of methyl vinyl ketone.
Searched for "synthesis of methyl vinyl ketone" 21 hits none involving Mannich reaction.
Have you got the link for the reference you gave, please?
