Notes: Reaction of di-tert-butylcyclopentadiene with excess potassium tert-butoxide in the presence of elemental selenium leads to cyclopentadienes bridged by two or three selenium atoms through one or two diselenoketal functionalities. 2,5,4′,6′-Tetra-tert-butyl-5′H-spirocyclopentane-1,2′-cyclopenta[b][1,3]diselena-2,4-diene (1) and 1,3,5,7-tetra-tert-butyl-3a,7a-dihydro-3a,7a-epi-selenodicyclopenta[b,e][1,4]diselenine (2) have been characterized by single-crystal X-ray diffraction.
