{{Further|Grignard reagent}}
Organomagnesium compounds are widespread in [[organic chemistry]]. They are commonly found as [[Grignard reagents]], formed by reaction of magnesium with [[haloalkane]]s. Examples of [[Grignard reagents]] are [[phenylmagnesium bromide]] and [[ethylmagnesium bromide]]. The [[Grignard reagents]] function as a common [[nucleophile]], attacking the [[electrophilic]] group such as the carbon atom that is present within the polar bond of a [[carbonyl]] group.

A prominent organomagnesium reagent beyond Grignard reagents is [[magnesium anthracene]], which is used as a source of highly active magnesium. The related [[butadiene]]-magnesium adduct serves as a source for the butadiene dianion.

Complexes of dimagnesium(I) have been observed.<ref>{{cite journal |last1=Rösch |first1=B. |last2=Gentner |first2=T.
