ring fission upon reaction with chlorocarbene in tetrahydrofuran. Acetylenes (12 and 18) are the result. The reaction of 1 is accompanied by ring enlargement to indolizine (7). When the reaction of 1 with chlorocarbene is performed in diethylether, again 7 is produced, this time accompanied by a tetracyclic valence isomer, the pyrroloazabenzvalene (8). Mechanistic implications, based on the finding
