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.
