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.
