A general term for reactions involving organomagnesium compounds represented by RMgX (R is an organic atomic group such as an alkyl group or a phenyl group, and X is Cl, Br, or I). This reaction involves organometallic compounds and was developed in 1901 by FAV Grignard of France. When metallic magnesium is reacted with an alkyl halide in a dry ether solvent, a Grignard reagent is obtained in high yield. There is much discussion regarding the state of existence of the reagent obtained in this way, and depending on the solvent, it may form a complex with the solvent or exist as a dimer.

RMgX(Rはアルキル基,フェニル基などの有機原子団,XはCl,Br,I)で表される有機マグネシウム化合物が関与する反応の総称。1901年フランスのF.A.V.グリニャールにより開発された有機金属化合物が関与する反応である。ハロゲン化アルキルに乾燥エーテル溶媒中金属マグネシウムを作用させるとグリニャール試薬が高収率で得られる。こうして得られた試薬は,その存在状態に関してはさまざまな議論があり,溶媒によっては溶媒との錯体を形成したり,二量体として存在する。
