1,5-HEXADIYNE Usage And Synthesis

Uses

1,5-Hexadiyne is used in the preparation of bisdehydro[12]annulene and biphenylene. It is also used as an important starting material in the preparation of (5Z,9Z)-5,9-hexadecadienoic acid. Further, it is involved in the preparation of linear organotin polymers by reaction with organotin dihydrides.

Definition

ChEBI: Hexa-1,5-diyne is an alkadiyne and a terminal acetylenic compound.
