Abstract

Abstract 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 cyclopropenyldiazomethanes are fragmented into the corresponding acetylenes.
