Hi there =)
Well, my class is currently dealing with arenes (and their reactions), we've got some homework and I need help >.<
Actually, I have solved the main synthesis task, which, if I am correct, leads to azulene.
The latter reacts with a few other substances, yet I don't know how
1) Azulene reacts with tert-butanol, catalysed by an acid, in a substitution reaction to F.
2) With an alkali organyl or a Grignard reagent azulene reacts in an
addition reaction to form a salt. This, after an aqueous preparation and oxidation with tetrachloro-para-benzo-quinone, becomes a respective alkyl substituted derivative of azulene.
Two different products (isomers) are possible. The first (G) emerges from the usage of methyllithium, the second (H) from the usage of triphenylmethyllithium.
3) Also compounds of transition metal of azulene are synthesisable. If azulene reacts with LiAlH
4 and Iron(II)-chloride, a red compound I is formed in the form of multiple stereoisomers.
Via careful hydrogenation of the isomers a single orange compound of J is formed with the empirical formula C
20H
26Fe.
My homework is to draw the chemical structure of F, G and H, as well as to draw all isomers of I and the chemical structure of J. But since I don't feel confident about the reactions or the products
, I can't do it
I would be deeply grateful if you helped me
