용도

cis-Cyclooctene is used as a displaced ligand in chlorobis(cyclooctene)rhodium dimer and chlorobis(cyclooctene)iridium dimer in organometallic chemistry. It acts as a monomer used in synthetic chemistry. It is used to prepare 1-chloro-4-(trichloromethyl) cyclooctane by reaction with carbon tetrachloride using dichlorotris(triphenylphosphine) ruthenium(II) as a catalyst. Further, it is used to study the alkenes chemisorbed on silicon(100) by scanning tunneling microscopy.

참고

Air sensitive. Incompatible with strong oxidizing agents.

The epoxidation of alkenes by H2O2 in methanol in the presence of acetonitrile is described for cyclooctene. The active species is the peroxyimidic acid, and the reaction is, with proper precautions, suitable for scale-up: Org. Synth. Coll., 7, 126 (1990).
