3-Chlorobenzonitrile is an organic compound with the chemical formula ClC6H4CN.

Typically, aryl nitriles are produced by ammoxidation.

[3] It can also be produced by heating 3-chlorobenzylamine and iodine in ammonium acetate aqueous solution.

[4] In the presence of copper nanoparticles, 3-chlorobenzonitrile can be reduced by sodium borohydride to 3-chlorobenzylamine.

[5] Some ruthenium catalyzers can catalysis the hydrolysis of 3-chlorobenzonitrile to form 3-chlorobenzamide.
