Grignard Reaction
Professor Dave Explains・2 minutes read
Grignard reactions involve alkyl halides reacting with magnesium to create a nucleophilic carbon that forms new covalent bonds with carbonyl compounds, expanding the carbon structure. These reactions must be done in anhydrous conditions to prevent reagent destruction by water, allowing for the production of alcohols and larger molecules from various carbonyl-containing compounds.
Insights
- Grignard reactions, developed in 1912 and awarded a Nobel Prize, are essential for forming new carbon-carbon bonds by creating a nucleophilic carbon via magnesium insertion into alkyl halides.
- Strictly anhydrous conditions are vital for Grignard reactions to avoid reagent destruction by water, enabling the nucleophilic carbon in Grignard reagents to form covalent bonds with carbonyl carbons in compounds like aldehydes and ketones, leading to the synthesis of alcohols and larger molecules.

"Grignard Reactions: Creating Carbon-Carbon Bonds"
- Grignard reactions are crucial for creating new carbon-carbon bonds, with the reaction developed in 1912 and winning a Nobel Prize.
- The reaction involves alkyl halides interacting with magnesium in anhydrous conditions, resulting in magnesium inserting itself into the carbon-halogen bond.
- This creates a rare nucleophilic carbon, known as a Grignard reagent, which reacts with carbonyl compounds like aldehydes and ketones.
- The nucleophilic carbon in the Grignard reagent forms a new covalent bond with the carbonyl carbon, generating a larger carbon skeletal structure.
- Grignard reactions must be conducted in strictly anhydrous conditions to prevent destruction of the reagent by water molecules.
- Grignard reagents can react with various carbonyl-containing compounds, such as aldehydes, ketones, and esters, to produce alcohols or larger molecules.
