The grignard reaction grignard is most noted for devising a new method for generating carbon-carbon bonds using magnesium to couple ketones and alkyl halides this reaction is valuable in organic synthesis. Grignard reaction grignard reagents the grignard reaction is the addition of an organomagnesium halide (grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. The grignard reaction (pronounced / ri ar/) is an organometallic chemical reaction in which alkyl- or aryl-magnesium halides (grignard reagents) attack electrophilic carbon atoms that are present within polar bonds (for example, in a carbonyl group as in the example shown below.
