Partial Bond Fixation in Naphthalene

Click For Summary
SUMMARY

The discussion centers on the reactivity of naphthalene, specifically the preferential reaction of ozone with the 1-2 bond over the 2-3 bond, as outlined in March's Advanced Organic Chemistry. It confirms that the ozonolysis reaction involves breaking the 1-2 bond and forming a carbonyl group, similar to ethene's reaction with ozone. The inquiry raises questions about the accuracy of the author's specified reaction, suggesting that a simple electrophile would lead to a substitution reaction at position 1.

PREREQUISITES
  • Understanding of resonance structures in organic chemistry

From the resonance structures of Naphthalene, 1-2 Bond has more double Bond character than 2-3 Bond.

In March's Advanced organic chemistry, its given that ozone preferentially reacts with 1-2 Bond. But the reaction is not given. Is this a normal ozonolysis reaction in which the 1-2 Bond is broken and replaced with a carbonyl group? (Like the reaction of ethene with ozone to form formaldehyde)

So ozone reacted with 1-2 and 3-4 Bond. So is the reaction specified by the author wrong?
If a simple electrophile was used, then there will be substitution reaction at position 1.
