AI Thread Summary
The discussion centers on the feasibility of a Diels-Alder reaction occurring with a non-conjugated diene, provided it has the correct geometric configuration for electron transfer. Participants acknowledge that while the proposed configuration may be implausible due to steric hindrance from hydrogen atoms, there is a possibility for Diels-Alder-like reactions to occur through non-synchronous mechanisms involving radicals. The legitimacy of such reactions is supported by references to published examples in the literature, indicating that alternative pathways can facilitate similar outcomes even in non-conjugated systems.

Can a reaction like the diels alder reaction occur if the diene is not conjugated, but can have the proper geometric configuration for the same electron transfer?

If my question is unclear, I can clarify further if necessary.

I think so, but note that in your example there are two hydrogens pointing towards each other which makes the relevant conformation implausible.
On the other hand, if I remember correctly, Diels Alder like reactions may also happen non-synchronously via a mechanism involving radicals, maybe that's more plausible in that case.
 
Yes, the reaction you have on the paper is legitimate.
 
I agree. I have seen such examples published.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
