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....

Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...
