An iridium atom in a bridgehead position is the most unusual feature of 2 , which was obtained in place of the anticipated carbene vinylidene complex upon reaction of 1 with propiolic acid. Equally surprising is the fact that 2 must be regarded as an oxonium system rather than as a carbene, the most obvious resonance alternative. R CO 2 CH 3 .
