Applications
5-Hexynenitrile is used in the preparation of annelated symmetric and asymmetric 3,3′-disubstituted 2,2′-bipyridines by cobalt(I)-catalyzed [2+2+2] cycloadditions with 1,3-diynes. Further, it reacts with 3-bromo-pyridine to prepare 6-(3-pyridinyl)-5-hexynenitrile.

Solubility
Miscible with water.

Notes
Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong bases.
