Summary:
- Frustrated Lewis pairs (FLPs) are a type of metal-free catalyst that have been used in various chemical reactions for the past 20 years.
- FLPs are formed by combining a Lewis acid (electron-pair acceptor) and a Lewis base (electron-pair donor), which creates a unique reactivity that can be used to activate small molecules like hydrogen.
- The development of FLPs has led to new and efficient ways of carrying out chemical transformations without the need for traditional metal-based catalysts, which has important implications for sustainable chemistry and green chemistry.
