Transcribed Image Text:This image depicts a chemical reaction sequence involving an organic compound with a benzene ring and three ester groups. The reaction is outlined in a stepwise manner as follows:
1. **First Step**: The compound is reacted with sodium borohydride (NaBH₄) at 0.25 equivalents in the presence of water (H₂O). Sodium borohydride is typically used as a reducing agent.
2. **Second Step**: The product from the first step is then reacted with an organometallic reagent, namely butylmagnesium bromide (BuMgBr), at 1 equivalent, in an ether solvent (diethyl ether—CH₃CH₂OCH₂CH₃). This is commonly known as a Grignard reaction, where the Grignard reagent adds to carbonyl groups.
3. **Third Step**: Finally, the reaction mixture is treated with deuterium chloride (DCl) in deuterium oxide (D₂O). This step likely serves to quench the reaction and replace remaining reactive hydrogen atoms with deuterium atoms.
This sequence suggests a typical multi-step organic synthesis aimed at reducing and subsequently modifying the original ester groups, possibly transforming them into alcohols and further extending the carbon chain in the molecule.
