| Abstract: | Treatment of 1,3,5‐tris(trifluoromethyl)benzene with n‐BuLi, followed by H3B?SMe2 and subsequent hydride removal gave the (Fmes)BH2 reagent, which was isolated as a SMe2 stabilized monomer or a ligand free (μ‐H)2‐bridged dimer. Reaction with Mes2P(vinyl) gave the respective ethylene‐bridged P/B(Fmes)H FLP. It reduced carbon monoxide to the formyl stage and carbon dioxide to the formaldehyde oxidation state. Most new compounds were characterized by X‐ray diffraction. |
