Hi,

I recently saw a following, small question, where I really wasn't sure about:
What would happen to 3-methyl 1,3,9 decatriene is we would heat it up (nothing else present in the solution) ?
1,3,9 decatriene  :delta: ?

I was thinking it would spontaneously form two bound 6-cyclic & 5-cylcic structure.

Thx in advance

You are on the right track, are you suggesting bicyclo[4.3.0]non-2-ene? I think you have lost a carbon atom in your molecule, have another shot...

No no, more something like this :

Can you draw a sensible mechanism for that reaction? You are not on the right track.

How to dienes normally react with alkenes when heated?

No no, more something like this :

Think about Diels-Alder reactions
