Here's a breakdown of the reaction:
1. Ozonolysis: Ozone (O3) reacts with the double bond in cyclohexene, forming a cyclic molozonide intermediate. This intermediate is unstable and quickly rearranges to form an ozonide.
2. Ozonide Reduction: The ozonide is then reduced with a reducing agent like zinc and acetic acid or dimethyl sulfide. This reduction cleaves the ozonide, breaking the double bond and forming two carbonyl groups.
Overall Reaction:
Cyclohexene + O3 → Hexanedial

Products:
The final product of cyclohexene ozonolysis is hexanedial:
```
O=C-H

O=C-H
```
Key Points:
* Ozonolysis is a powerful tool for cleaving double bonds and forming carbonyl compounds.
* The specific reducing agent used can affect the yield and selectivity of the reaction.
* Hexanedial is a useful intermediate for organic synthesis.
