Reaction of phenol with grignard reagent
WebGrignard reactions are performed using a Grignard reagent, which is typically a alkyl-, aryl- or vinyl- organomagnesium halide compound. To ensure optimization and safety of Grignard reactions in research, development and production, in situ monitoring and understanding reaction heat flow is important. Hydrogenation Reactions WebFeb 3, 2024 · In the second reaction, I reacted the Grignard reagent with benzophenone, my limiting reagent, to form an alkoxide intermediate, to which I added excess 6M HCl to protonate the intermediate to form crude triphenylmethanol. I then performed a recrystallization of the crude triphenylmethanol (with biphenyl as a by-product) with …
