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).
Catalytichydrogenation that utilizes frustratedLewispair (FLP) catalysts is a subject of growing interest because such catalysts offer a unique opportunity for the development of transition‐metal‐free hydrogenations. The aim of our recent efforts is to further increase the functional‐group tolerance and chemoselectivity of FLP catalysts by means of size‐exclusion catalyst design. Given that hydrogen
