Introduction In this experiment, we will be performing a Grignard reaction. This reaction is a nucleophilic addition between a Grignard reagent and a carbonyl compound. This is very useful because it can form a carbon-carbon bond. A Grignard reagent is an alkylmagnesium halide that is produced by reacting magnesium with an alkyl halide, alkenyl halide, or an aryl halide. In this experiment, we will be preparing an alcohol (triphenylmethanol) by synthesizing phenylmagnesium bromide (the Grignard reagent) and reacting it with the carbonyl compound, benzophenone.
