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....

Butanone undergoes a nucleophilic addition with a Grignard reagent made from 1-bromopropane and magnesium metal in THF solution. The alkoxide formed from the nucleophilic addition is then conveted into the final product by the careful addition of dilute acid. Complete the mechanism by adding curved arrows and drawing final product. Show all lone-pairs and charges. Nucleophilic Addition Add a series of curved arrows to the sketch to demonstrate a nucleophilic addition. Draw the alkoxide intermediate. Acid workup Use curved arrows...
