2‐Bromo[5]helicene derivatives and substituted [7]helicenes have been prepared through a synthetic sequence relying on Heck‐type and photocyclodehydrogenation reactions. This procedure provides a new, versatile and efficient approach to helicene derivatives. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
