title: Synthesis of hexadehydrotribenzo[a,e,i][12]annulenes by acetylene insertion into an open-chain precursor.
abstract: A simple synthesis of a hexadehydrotribenzo[a,e,i][12]annulene by insertion of acetylene into an open-chain diiodo precursor under Sonogashira coupling conditions has been developed and used to prepare a rigid three-armed star connector for testing as a building block for a two-dimensional hexagonal hydrogen-bonding array.
