Organometallic reagents such as Grignard reagents, organolithium reagents and acetylides have two primary behaviors: 1) they act as strong bases, and 2) they act as strong nucleophiles. When they come into contact with any OH group they always act as a base and deprotonate the OH proton. Draw in curved arrows to show this deprotonation in the reactions below. Then, draw the missing organic products in each reaction.

Grignard and organolithium reagents are powerful bases. Because of this, they cannot be used as nucleophiles on compounds which contain acidic hydrogens. If they are use, they will act as a base and deprotonate the acidic hydrogen rather than act as a nucleophile and attack the carbonyl. A partial list of functional groups which cannot be used are: alcohols, amides, 1o amines, 2o amines, carboxylic acids, and terminal alkynes. Determine the product of a reaction in which one of the...

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....
