noun ˈdʌɪiːnˈdīēn

Chemistry

An unsaturated hydrocarbon containing two double bonds between carbon atoms.
〔化〕二烯（烃）
Example sentencesExamples
- They found that the lead catalyst was effective in reacting the well known Si-containing reagent Danishefsky's diene with various aldehydes to produce dihydropyrone hetero-cycles.
- The formation of conjugated dienes occurs when free radicals attack the hydrogens of methylene groups separating double bonds and leading to a rearrangement of the bonds.
- They established that the conjugated triene was further hydrogenated to a non-conjugated diene and eventually to the monoene 18.
- While supplementation was able to reduce thiobarbituric reactive substances, it was only able to slightly lower the quantity of conjugated dienes formed.
- They had reacted a conjugated diene with a simple alkene to generate a cycloalkane.

Origin
