| | DI-TERT-BUTYLCYCLOPENTADIENE Usage And Synthesis |
| Uses | Di-tert-butylcyclopentadiene may be used in the preparation of 2,5,4′,6′-tetra-tert-butyl-5′H-spirocyclopentane-1,2′-cyclopenta[b][1,3]diselena-2,4-diene and 1,3,5,7-tetra-tert-butyl-3a,7a-dihydro-3a,7a-epi-selenodicyclopenta[b,e][1,4]diselenine. | | General Description | Preparation of di-tert-butylcyclopentadiene by phase-transfer-catalyzed alkylation has been reported. It reacts with excess potassium tert-butoxide in the presence of elemental selenium to yield cyclopentadienes bridged by two or three selenium atoms through one or two diselenoketal functionalities. It reacts with excess potassium tert-butoxide in the presence of elemental sulfur to yield cyclopentadienes bridged by sulfur atoms via one or two dithioketal functionalities. |
