Abstract
A new and efficient method for the ‘one-step’ synthesis of (Z)-1,2bis(benzodithienyl)ethenes has been set up using double Suzuki coupling between stereochemically defined diboronic acid esters and 2-iodobenzodithiophene. The new Z-alkenes thus obtained can be easily and efficiently photochemically cyclised to the newly substituted tetrathia[7]helicenes.
