Abstract
Abstract The hydrocarbon, 1-(propan-2-ylidene)-1a,9b-dihydro-1H-cyclopropa[l]phenanthrene, affords dimethylvinylidene upon photolysis (∼315–400 nm) at ambient temperature, and the carbene may be trapped by cyclohexene. Some of the precursor also rearranged to a non-photolabile isomer via a putative 1,5-sigmatropic shift followed by an electrocyclic ring opening.
