Data for the synthesis of triphenylmethanol using a Grignard reagent The IR spectrum was useful in confirming the identity, as well as purity of the synthesized product. The reaction was allowed to continue steadily for 15 minutes until all the magnesium dissolved and the contents turned brown/cloudy. Aldehydes and ketones react strongly with the Grignard reagent via nucleophilic acyl addition mechanism forming alcohol as the product. Electrophilic functional groups such as carbonyl-containing compounds, alkyl halides, and alcohols readily react with the Grignard reagent through nucleophilic acyl addition and nucleophilic acyl substitution mechanism.
