Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

Preparation of Triphenylmethanol Using the Grignard Reaction.
RH ROOH CO TO R-R MgBr 1.ether 2.11-SO/10 Icther Grignard reagents are highly reactive and can undergo undesirable RCOH TH₂O side reactions if impurities such as water, carbon dioxide, or oxygen are present. If the organohalogen is added to the R-Mg-X magnesium too quickly, undesired coupling reactions can also occur. In this experiment, you will use 0.015 moles of either benzophenone or ethyl benzoate as the recipient of the phenylmagnesium bromide and this...

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...
