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....

(CH3)2Culi + CH3Cu Ph CI Ph CH3 The ketone intermediate formed in the reaction of an acid chloride with a Grignard reagent cannot be isolated because it reacts too rapidly with the second equivalent of Grignard reagent. To produce a ketone from an acid chloride, one can treat the acid chloride with a lithium dialkylcopper reagent. The reaction occurs by nucleophilic acyl substitution on the acid chloride by the dialkylcopper anion to yield an acyl...
