Objectives: Synthesize triphenylcarbinol by Grignard rxn. Understand the mechanism of Grignard rxn and learn the technique of performing experiments in anhydrous condition.
Principles & Methods
This exp is a rxn to synthesize triphenylcarbinol by Grignard rxn. So, let's get to know Grignard rxn first. Grignard rxn allows the formation of carbon-carbon bonds using organometallic intermediate(Grignard reagents). Grignard reagents are prepared by reacting magnesium metal with alkyl or aryl halides in aprotic solvents such as diethyl ether or tetrahydrofuran(In our exp, we use diethyl ether). They have a carbon-metal bond, which changes the polarity of a carbon atom from the partial positive charge(in aryl and alkyl halides) to the partial negative charge in Grignard reagents.
