Abstract
The reaction of 2-phenyl-2-(1,2-diphenyl-3-cyclopropenylidene)acetonitrile with 1-(1-pyrrolidinyl)acenaphthylene giving two isomeric tetrahydroindeno[1′,2′]cyclopenta[4,5-a]acenaphthylenes is the first example in which a phenyl group on the methylenecyclopropene ring took part in a cyclization: They are presumed to form via the regioselective Cope rearrangement of initially formed endo [2+2] cycloadducts followed by a hydrogen shift.
