The organometallic reagent(s) among the following is(are)
Show Hint
- Lithium divinylcuprate
- Lithium diisopropylamide
- Potassium tert-butoxide
- Isopropyl magnesiumiodide
The Correct Option is A, D
Solution and Explanation
Step 1: Understanding organometallic reagents.
Organometallic reagents typically contain a metal-carbon bond, where the metal is typically a metal from group 1, 2, or 3 of the periodic table. Common examples include Grignard reagents and organocuprates.
Step 2: Analyzing the options.
- Option (A) Lithium divinylcuprate is an organocuprate, which is an organometallic reagent.
- Option (B) Lithium diisopropylamide is not organometallic, as it contains no metal-carbon bond.
- Option (C) Potassium tert-butoxide is not organometallic, as it involves a potassium-oxygen bond.
- Option (D) Isopropyl magnesium iodide is a Grignard reagent, which is a typical organometallic compound.
Step 3: Conclusion.
The correct organometallic reagents are (A) and (D).
