Starting from 2-bromotri-tert-butylcyclopentadienone (1) a series of highly substituted cyclopentadienones has been prepared, hoping that they might be suitable candidates for the synthesis of a variety of tetrahedranes with different sterically demanding substituents. - Key Words: Nucleophilic addition / Sigmatropic rearrangement / Steric hindrance

Reaction of tri-tert-butylcyclopropenylium tetrafluoroborate 7 with the Li-salt of tert-butyldiazomethane leads to the astonishingly stable diazo compound 6.The trimethylsilyl derivative 8 can be prepared via the same route.On photolysis or pyrolysis both
