Highly versatile procedures have been developed for the synthesis of functionalized tetrathia[7]helicenes, including benzo fused systems, through transition metal‐promoted annulation reactions of bis(benzodithiophene) species, obtained from 2‐bromo‐3,3′‐bibenzo[1,2‐b:4,3‐b′]dithiophene as key intermediate.
