Applicazioni

2,5-Norbornadiene is used as an intermediate in prostaglandin synthesis and shows anti-ethylene effect on plants. It acts as a starting material for the synthesis of diamantane and as an acetylene transfer agent for instance, in reaction with 3,6-di-2-pyridyl-1,2,4,5-tetrazine. It is also a useful dienophile in Diels-Alder reactions.

Note

Incompatible with strong oxidizing agents, strong acids and strong bases.

The 2,4-pentanedionatorhodium complex: J. Chem. Soc. (A), 2334 (1971) has been used in the preparation of a chiral BINAP catalyst for homogeneous asymmetric hydrogenation: Org. Synth. Coll., 8, 420 (1993); see also (R)-(+)-2,2'-Bis(diphenyl­phosphino)-1,1'-binaphthyl­, B23785.

Cycloaddition with Tetraphenyl­cyclopentadienone, A12756, is followed by retro-Diels-Alder reaction with loss of cyclopentadiene to give 1,2,3,4-tetraphenylbenzene: J. Chem. Soc., 473 (1960).

Similarly, pyrolysis of the adduct formed by 1,3-dipolar cycloaddition of acrylonitrile oxide provides a high-yield route to 3-vinylisoxazole: J. Chem. Soc., Chem. Commun., 2661 (1994).
