Using the Grignard Reaction to Make Tertiary alcohols
In this video we make tertiary alcohols using the (in)famous Grignard reaction.
Briefly, an alkyl halide is reacted with magnesium metal to form an organometallic alkyl magnesium halide. This is the grignard reagent. This reagent is then reacted with a carbonyl containing compound suck as a ketone, an ester or an organic carbonate to form a tertiary alcohol. The mixture is then reacted with water and titrated with acid to dissolve the magnesium hydroxides formed. Finally, the alcohol is purified by a series of liquid extractions and distillations.
