5-CYANO-1-PENTYNE Usage And Synthesis

Chemical Properties

clear colourless to amber liquid

Uses

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.
