Grignard Reaction with Formaldehyde

CH₃MgBr + HCHO → CH₃CH₂OH (after hydrolysis)

अवलोकन

A Grignard reagent (methylmagnesium bromide) adds to formaldehyde, and after aqueous workup produces a primary alcohol. Grignard reagents are organomagnesium halides that act as powerful nucleophilic carbon sources. The reaction must be performed in anhydrous ether because Grignard reagents react violently with water.
