Ketones are also prepared by reaction
of acyl chloride with dialkylcadmium 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),
