Grignard Reaction with Formaldehyde

CH3MgBr + HCHO → CH3CH2OH (after hydrolysis)

개요

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.
