In a recent article, we observed that ketiminium (1) and aldiminium (2) salts reacted with sodium bis(trimethylsilylamide) to yield products which contained aziridine rings.

heptafulvene, 8, undergoes both an intramolecular [8+21 cycloaddition and a loll-electron electrocyclization followed by 1,5-sigmatropic hydrogen shifts to give 10 and 12, respectively. Acetylheptafulvene, 1, was reported to be unstable by Hafner,' although the reaction of 1 with DMAD to give an in
