Organometallic coupling reaction
A solution of a carbonyl compound is added to a Grignard reagent. (See gallery)The Grignard reaction (
French: [ɡʁiɲaʁ]) is an organometallic chemical reaction in which carbon alkyl, allyl, vinyl, or aryl magnesium halides (Grignard reagent) are added to the carbonyl groups of either an aldehyde or ketone.[1][2] This reaction is important for the formation of carbon–carbon bonds.[3][4](R2 or R3 could be a hydrogen)
Grignard reactions and reagents were discovered by and are named after the French chemist François Auguste Victor Grignard (University of Nancy, France), who published it in 1900[5] and was awarded the 1912 Nobel Prize in Chemistry for this work.[6] The reaction of an organic ha...
