Frustrated Lewis pairs (FLPs) are unique chemical species composed of a Lewis acid and a Lewis base that are prevented from combining due to steric hindrance. This creates a highly reactive system where the acid and base are poised to react but are held apart. FLPs exhibit remarkable reactivity and have found applications in various catalytic processes, including hydrogen activation, olefin polymerization, and cross-coupling reactions. Metal-frustrated Lewis pairs (M-FLPs) are FLPs that incorporate a metal ion, further enhancing their reactivity and catalytic properties.
