Norbornadiene is an bicyclic hydrocarbon. The molecule can be envisioned as a 1,4-cyclohexadiene bridged in the para positions by a methylene group. The compound is related to norbornene in which one of the double bonds is saturated. Norbornadiene and related compounds are of great scientific interest because of the unusual geometry and high reactivity.

Synthesis
The norbornadiene framework is based on a Diels-Alder reaction between a cyclopentadiene and an alkyne. The Diels-Alder reaction is an organic chemical reaction (specifically, a cycloaddition) between a conjugated diene and a substituted alkene, commonly termed the dienophile to form a substituted cyclohexene system. ...

Reactions Quadricyclane is a norbornadiene isomer. It can be obtained from norbornadiene by a photochemical reaction when assisted by a sensitizer such as acetophenone. The norbornadiene quadricyclane couple is of potential interest for solar energy storage when controlled release of the strain energy stored in quadricyclane back to norbornadiene is made possible 1 . Quadricyclane is very reactive towards dienophiles in cycloaddition reactions.

Norbornadienes also form organometallic sandwich compounds such as tetracarbonyl(norbornadiene)chromium(0) 3. This complex is a useful reagent which transfers chromium tetracarbonyl to bidentate phospine ligands. Organometallic have classically been compounds having bonds between one or more metal atoms and one or more carbon atoms of an organyl group. ...
