摘要：
The hydrocarbon, 1-(propan-2-ylidene)-1a,9b-dihydro-1H-cyclopropa[l]phenanthrene, affords dimethylvinylidene upon photolysis (similar to 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. (C) 2015 Elsevier Ltd. All rights reserved.
