heterogeneous systems, has not yet been achieved. Herein, we demonstrate that, via tailoring the pore environment within metal–organic frameworks (MOFs), FLPs not only can be stabilized but also can develop interesting performance in the chemoselective hydrogenation of α,β‐unsaturated organic compounds, which cannot be achieved with FLPs in a homogeneous system. Using hydrogen gas under moderate pressure

MesB(C6F5)(2) (1) has been prepared from MesMgBr and FB(C6F5)(2)(OEt2)-O-., while Mes(2)B(C6F5) (2) is readily available from CuC6F5 and Mes(2)BBr. The reduction potential E degrees of 1 vs Cp2Fe0/+ in THF is - 1.72 V, while that of 2 is -2.10 V, and that Of Mes(3)B (3) is -2.73 V. B-11 and H-1 NMR show that neither I nor 2 binds THF significantly. These results have been used to estimate the reduction potential of B(C6F5)(3) in THF as -1.17 V vs Cp2Fe0/+ or as -0.64 V vs SCE.

No metal causes frustration: Based on a conceptual framework, novel frustratedLewis acid–base catalyst systems with orthogonal reactivity have been developed. Aside from enhanced functional‐group tolerance, unique chemoselectivity can be achieved in catalytic metal‐free hydrogenations (see scheme).
