Homework Answers
(a)
Step 1: Bromination of benzene via electrophilic aromatic substitution.
Step 2: Production of Grignard reagent.
Step 3: Formation of secondary alcohol from the reaction of Grignard reagent with benzaldehyde.
Step 4: Oxidation of secondary alcohol to ketone.
(b)
Step 1: Formation of Grignard and then reaction of Grignard reagent with CO2 followed by acidic work up gives carboxylic acid.
Step 2: Formation of acid to acid chloride. Then acid chloride reacts with ammonia to form amide.
Step 3: Dehydration of amide with phosphorous pentoxide gives the nitrile.
(c)
Step 1: Aldol reaction gives the aldol product.
Step 2: Dehydration of aldol product to give the conjugated aldehyde.
Step 3: Reduction of aldehyde to alcohol.
(d)
Step 1: Oxidation of toluene to benzoic acid.
Step 2: Conversion of acid to acid chloride.
Step 3: Reduction of acid chloride to aldehyde.
