Abstract

original image

Character sketch: Boracyclophanes, in which the benzene ring coordinates to the boron atom, were synthesized. X-ray crystallographic analysis and theoretical calculations revealed the intrinsic character of the boron–benzene interaction. Its σ/π character can be modulated by changing the electron-donating character of the benzene ring.
