Abstract
While 10,10-diphenyl-9-(10 H )-phenanthrenone ( 1 ) is inert under conventional irradiation conditions, it undergoes decarbonylation under high-intensity argon laser-jet conditions to form 9,9-diphenylfuorene ( 3 ) and the cycloheptatriene 4 . Molecular modeling studies indicate that 3 arises from collapse of the singlet carbene 1 5 and the triene 4 from the triplet carbene 3 5 .
