### Reaction Mechanism Overview

**Starting Material**:

- The reaction begins with an unspecified substrate placed in a bounded rectangle marked by the number [3].

**Reaction Steps**:

1. **Reagents and Conditions**:
- **PPh₃ (Triphenylphosphine), 1.0 equivalent**: This reagent is involved in the formation of a phosphonium ylide, a key intermediate in Wittig reactions.
- **nBuLi (n-Butyllithium), 1.0 equivalent**: A strong base, n-Butyllithium, is used to deprotonate a phosphonium salt to form the corresponding ylide.

2. **Mechanism**:
- An arrow is shown directing from the starting material to the products, indicating the progression of the reaction. The addition of PPh₃ and nBuLi facilitates the conversion of the substrate.

3. **Products**:
- The structure on the right shows a cyclic compound with a double bond and a keto group, along with an alkyl chain. This product results from the reaction of the ylide with a carbonyl compound.
- Additional by-products include **O=PPh₃ (Triphenylphosphine oxide)** and **LiBr (Lithium bromide)**.

The entire setup corresponds to a typical preparation and reaction sequence, effectively illustrating principles of organophosphorus chemistry and practical aspects of synthetic methodology in organic chemistry.
