What is the Grignard reaction?
Q: What is the Grignard reaction?
A: The Grignard reaction is an organometallic chemical reaction in which alkyl- or aryl-magnesium halides (Grignard reagents) attack electrophilic carbon atoms that are present within polar bonds.
Q: What type of bond does the Grignard reaction produce?
A: The Grignard reaction produces a carbon–carbon bond.
Q: What other types of bonds can be formed using the Grignard reaction?
A: The Grignard reaction can also form carbon–phosphorus, carbon–tin, carbon–silicon, carbon–boron and other carbon–heteroatom bonds.
Q: How does the high pKa value of the alkyl component affect the Grignard reaction?
A: The high pKa value of the alkyl component (pKa = ~45) makes the reaction irreversible.
Q: What type of addition reactions do Grignard reagents take part in?
A: Grignard reagents take part in nucleophilic organometallic addition reactions.
Q: What are some disadvantages associated with using Grignard reagents? A: Some disadvantages associated with using Grignard reagents include their reactivity with protic solvents such as water and functional groups with acidic protons, such as alcohols and amines; sensitivity to atmospheric humidity; and difficulty forming carbon-carbon bonds by reacting with alkyl halides by an SN2 mechanism.
Q: Who discovered the Grigand Reaction and Reagents?
A:The discovery of the Griand Reaction and Reagent is attributed to French chemist François Auguste Victor Griand who was awarded the 1912 Nobel Prize in Chemistry for this work.
