A bit borane : Silicon‐functionalized dibenzosilaborins were prepared by intramolecular BH/CH dehydrogenative cyclization of o ‐(silyl)(hydroboryl)benzenes. The hydrosilyl derivative (X=H) can be converted into the fluorosilane (X=F) and chlorosilane (X=Cl). UV/Vis and fluorescence spectra are influenced by the functional groups X on the silicon atom through σ*–π* conjugation.
