| 1,5-CYCLOOCTADIENE Usage And Synthesis |
| Uses | 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
| | General Description | 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. | | Purification Methods | Purify it by GLC. It has been purified via the AgNO3 salt. This is prepared by shaking with a solution of 50% aqueous AgNO3 w/w several times (e.g. 3 x 50mLand4x50mL) at 70ofor ca 20minutes to get a good separation of layers. The upper layers are combined and further extracted with AgNO3 at 40o (2 x 20 mL). The upper layer (19 mL) of original hydrocarbon mixture gives colourless needles of the AgNO3 complex on cooling. The adduct is recrystallised from MeOH (and cooling to 0o). The hydrocarbon is recovered by steam distilling the salt. The distillate is extracted with Et2O, dried (MgSO4), filtered, evaporated and distilled. [Jones J Chem Soc 312 1954,[Beilstein 5 H 116, 5 IV 403.] |
