Non-conjugated tetraynes 1 undergo thennal intmmolecul~ cyclization to non-benzenoiddiradicals (23) followed by radical cycloaromatization at 25 ~C to provide 7-dehydro-5H-benzo[d]fluoreno[3,2-b]pyran monoradical (2 4) and alkyl radicals (2 5). Hydrogen abstraction of 2 4 gives 5H-benzo[d] fluoreno[
