Organic Chemistry: C-C Bond forming Reactions



One of the most important reactions in organic chemistry are the C-C bond forming reactions. Following are some of the reactions for forming a single bond between carbon atoms.

 

1.   Aldol Condensation

Aldol condensation is the reaction in which an enolizable aldehyde or ketone condenses with another aldehyde or a ketone to form an aldol followed by dehydration to yield a,b-unsaturated carbonyl compounds. The reaction is carried out under basic or acidic conditions and the prerequisite is the presence of an a-hydrogen in the aldehyde.

The reaction goes through an enolate (base catalyzed) or enol (acid catalyzed) intermediate.



2.   Wurtz Reaction

Wurtz reaction is the coupling of alkyl groups in alkyl halides in the presence of a metal (Na).


 


3.   Friedel-Craft’s Alkylation and Acylation

Friedel-Craft’s alkylation and acylation are examples of aromatic electrophilic substitution reactions. It involves the reaction of an aromatic ring with alkyl or acyl halides in the presence of a Lewis acid.
