蒸气压： 25.8 mmHg ( 37.7 °C) 6.8 mmHg ( 25 °C) Surface grafting of cis,cis-1,5-cyclooctadiene (cyclic olefin) with low strain energy was explored using ring-opening metathesis polymerization in the vapor phase. The inclusion complex of cis,cis-1,5-cyclooctadiene with β-cyclodextrin (β-CD) was studied by using proton NMR spectroscopy. cis,cis-1,5-Cyclooctadiene (COD) has been employed as ligand: . during regio- and stereoselective synthesis of (Z)-1,2-dihaloalkenes . in the preparation of metal complexes, e.g. bis-COD-nickel, a versatile reagent for preparing (PI)-allylnickel halides
