James Mitchell Crow explains how an unexpected discovery in main group chemistry inspired two decades of chemical creativity, from carbon dioxide reduction to fluorocarbon recycling, offering sustainable alternatives to precious metal catalysis
Frustrated Lewis pairs began as an unexpected laboratory accident, but over the past two decades this quirky concept has transformed into one of the most versatile ideas in modern main group chemistry. From metal‑free hydrogen activation to asymmetric catalysis, radical reactivity and even selective carbon–fluorine bond editing, FLPs are revealing new ways to drive key reactions that once relied on precious metals. As researchers push the limits of their design and explore applications from CO₂ reduction to pharmaceutical radiolabelling and fluorocarbon upcycling, the field continues to evolve in surprising and sometimes radical directions.
