Give the major organic product(s) for the following reaction
Transcribed Image Text:### Organic Chemistry Reaction: Cyclohexanone Conversion
#### Reactants and Reagents:
- The starting compound is cyclohexanone, depicted as a six-membered cyclohexane ring with a ketone group (=O) attached to one of the carbon atoms.
- The first reagents added to the reaction are sodium cyanide (NaCN) and hydrogen cyanide (HCN).
- The second reagent added is hydrogen (H₂) in the presence of palladium (Pd) as a catalyst.
#### Reaction Process:
1. **First Step: Nucleophilic Addition**
- In the presence of NaCN and HCN, the carbonyl group of cyclohexanone undergoes nucleophilic addition.
- The result is the formation of a cyanohydrin, where the cyanide ion (CN⁻) adds to the carbonyl carbon and the hydroxyl group (OH) forms at the oxygen site.
2. **Second Step: Reduction**
- The cyanohydrin is then subjected to catalytic hydrogenation using hydrogen gas (H₂) and palladium (Pd) catalyst.
- This reduces the nitrile group (C≡N) of the cyanohydrin to a primary amine (CH₂-NH₂) group.
#### Product:
- The final product is a new compound where the former ketone of cyclohexanone has been converted first to a cyanohydrin and then to a primary amine via reduction.
This reaction illustrates a two-step sequence of nucleophilic addition followed by reduction, showcasing common techniques in synthetic organic chemistry to transform functional groups.
