‘Face‐to‐Face’ Benzo‐anellated Homologous Hypostrophenes. Syntheses, X‐Ray‐Structure Analyses and PE Spectra ‘Face‐to‐face’ Benzo‐anellated homologous hypostrophenes (series M ), of interest as substrates for [6 + 6]‐photocycloaddition reactions, have been synthesized. From X‐ray structural analyses of 13b and 13c shortest CC distances of 2.80(2.76)/2.71 Å and interorbital angles (ω) of 129° (128°)/130° between the benzene rings have been determined. The PE spectra are discussed in the context of transannular π,π interactions.
