A good method for the preparation of aromatic
ketones is the Friedel-Crafts acylation of aromatic hydrocarbons with acyl chlorides
or anhydrides Both aldehydes and ketones can be prepared by ozonolysis of alkenes Aldehydes and ketones undergo nucleophilic addition reactions onto the carbonyl
group with a number of nucleophiles such as, HCN, NaHSO3, alcohols (or diols),
2 Ring substitution
Aromatic carboxylic acids undergo electrophilic substitution reactions
in which the carboxyl group acts as a deactivating and meta-directing
group
