Grignard metathesis

Grignard metathesis, Grignard reaction the grignard reaction (pronounced /ɡriɲar/) is an organometallic chemical reaction in which alkyl, vinyl, or aryl-magnesium halides (grignard reagents) add to a carbonyl group in an aldehyde or ketone this reaction is an important tool for the formation of carbon–carbon bonds.
