The formation of a Grignard reagent usually takes place in an anhydrous ethereal solution between magnesium metal and either an aryl or an alkyl halide. In these reactions, the electophillic carbon on the halide bonds with the magnesium and becomes a nucleophillic carbon. The Grignard reaction is an organometallic chemical reaction in which alkyl, allyl, vinyl, or aryl-magnesium halides (Grignard reagent) is added to a carbonyl group in an aldehyde or ketone. This reaction is important for the formation of carbon–carbon bonds. The reaction of an organic halide with magnesium is not a Grignard reaction, but provides a Grignard reagent. recipe old bay shrimp
