[2.2]Metacyclo(1,3)azulenophane (4) has been synthesized in two steps from azulyl-1,3-bis(trimethylammonium) diiodide (1). The cyclophane 4 could be converted to the novel nonalternant hydrocarbon, azuleno[1,2,3-cd]phenalene (6), through the transannular coupling followed by dehydrogenation sequence. Some properties of 4 are also reported.
