I don’t think this will lead to an aldol reaction because hyperconjugation stabilizes the carbonyl such that enones don’t undergo 1,2-addition in the presence of most nucleophiles. google_ad_width = 120; But mostly, I just need a memory jogger now and then, or confirmation that yes, the intermediate is a carbocation and not an oxacyclopentane, or no, I haven’t lost my marbles and gotten a set of electron pushing arrows in the wrong spot. I think Grignard reagents are the most common exception, though. Since these reactions are mostly generalized are not only important from the view point of an academician but also play a crucial role for a practicing organic chemist in developing his/her routine modern organic synthetic strategies. I wonder if there might be a “view/print” option that allows you to see the name of the reaction (like you have above) with just a tidy concise example/mechanism below it.
