Gold-catalyzed hydroarylating cyclization of 1,2-Bis(2-iodoethynyl)benzenes

1,5-Diynes bearing halogen-substituted alkynes were synthesized and converted in the presence of a gold catalyst. In contrast to the corresponding hydroarylating aromatization reaction with terminal alkynes, a totally different reaction mode was observed.

Synthesis of hexadehydrotribenzo[a,e,i][12]annulenes by acetylene insertion into an open-chain precursor

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 b
