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.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
