The synthesis of 5‐bromopenta‐2,4‐diynenitrile (BrC5N) in three steps from commercially available compounds is reported. Reacting 5‐bromopenta‐2,4‐diynenitrile with secondary amines led to the formation of stable butadiynamines or enynenitriles, depending on the nature of the amine reactant. The reaction of 5‐bromopenta‐2,4‐diynenitrile with simple terminal alkynes in the presence of secondary amines
