No metal causes frustration: Based on a conceptual framework, novel frustrated Lewis 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).
