1,5-Hexadiene is theorganic compound with the formula (CH2)2(CH=CH2)2. It is a colorless, volatile liquid. It is used as acrosslinking agent and precursor to a variety of other compounds.
1,5-Hexadiene is produced commercially by theethenolysis of1,5-cyclooctadiene:[1]
The catalyst is derived fromRe2O7 on alumina.
A laboratory-scale preparation involves reductive coupling ofallyl chloride using magnesium:[2]
