文摘

The syntheses and structural characterization of sterically encumbered 1,2-diborylferrocenes are reported, together with an investigation of their anion recognition capabilities with respect to fluoride and cyanide. Surprisingly, 1,2-fc(BMes₂)₂ is found to be highly selective for CN⁻, with the uptake of F⁻ being shown to be not only thermodynamically less favorable but also kinetically much slower.
