The cyclobutenyl dichloride below reacts with the powerful Lewis acid antimony pentafluoride in liquid SO2 at -75o to give a pale yellow solution that exhibits one singlet at 3.68 ppm in its 1H-NMR spectrum. The species in solution has been deduced to be the salt C8H12X2 where X is an hexahaloantimonate anion.
Draw the cation part of the salt C8H12X2

Transcribed Image Text:The image depicts a chemical reaction involving an alkene reacting with antimony pentafluoride (SbF₅) in sulfur dioxide (SO₂) as a solvent at -75°C, resulting in a product with the molecular formula C₈H₁₂X₂, where X represents a hexahaloantimonate anion.
### Reaction Details:
- **Reactant:**
- The starting substance is a cyclobutane derivative with two chlorine atoms and two methyl groups.
- **Reagents and Conditions:**
- **SbF₅**: Antimony pentafluoride, a strong Lewis acid.
- **SO₂**: Sulfur dioxide, used here as the solvent.
- **Temperature**: The reaction is conducted at -75°C.
- **Product:**
- C₈H₁₂X₂: Indicates a molecular formula with unspecified anion X, identified as a hexahaloantimonate anion.
This reaction showcases the formation of a complex with carbon framework expansion and the incorporation of a hexahaloantimonate anion.
