Grignard Reagents These are of the formal type R-Mg-X. CHCH,OCH,CH 6 R-X+Mg R-Mg-X reacts like R:MgX (X=CI.Br,or I) organomagnesium halide (Grignard reagent) They are made via the reaction of metallic Mg with the corresponding alkyl halide,usually in ether type solvents. This reaction is versatile;primary,secondary and tertiary alkyl halides can be used,and also vinyl,allyl and aryl halides. Mg Mg- Ether Mg HgC-Br HaC-Mg-Br Ether Organolithium Reagents These are also formed via action of the metal with an alkyl halide R-X 2Li →Lit-X+R一Li reacts like R:Li (X CI.Br,or I) organolithium Unlike Grignard reagents,alkyl lithiums can be prepared and used in a variety of hydrocarbon solvents(hexane, pentane etc).
