| | 1,3-CYCLOHEPTADIENE Usage And Synthesis |
| Uses | 1,3-Cycloheptadiene was used in the preparation of enantiopure epoxy cycloheptenyl sulfones. | | General Description | 1,3-Cycloheptadiene is a 1,3-cycloalkadiene. Isomerization of highly strained (E,E)-1,3-cycloheptadiene was investigated through double bond rotation, and electrocyclic ring closure. [1,5] Sigmatropic hydrogen shifts in 1,3-cyclohepatdiene were studied by density functional calculations. | | Purification Methods | Purify the diene by dissolving it in Et2O, washing with 5% HCl, H2O, drying (MgSO4), evaporating, and the residue is distilled under dry N2 through a semi-micro column (some foaming occurs) [Cope et al. J Am Chem Soc 79 6287 1957, UV: Pesch & Friess J Am Chem Soc 72 5756 1950]. [Beilstein 5 IV 390.] |
