Grignard reagents cannot be generated in the presence of an alcohol, as the acidic hydrogen will quench the Grignard reagent as it is formed. Choose the appropriate protecting group, then draw the expected intermediates (with the protecting group drawn out) and final product in this sequence. All structures should be neutral; omit byproducts.

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....

Alkenes can be converted to alcohols by reaction with mercuric acetate to form a B-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C-Hg bond to a C-H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structures of the Hg-containing compound(s) and the final alcohol product(s) formed in the following reaction sequence, omitting byproducts. If applicable, draw hydrogen at a chirality center and indicate stereochemistry via wedge-and-dash bonds. Draw 2 Neutral product(s) of...
