Abstract
Recent progress in frustrated Lewis pair (FLP) chemistry has revealed the importance of the main group elements which has opened new avenues in synthetic chemistry. Recently, new reactivities of frustrated Lewis pairs have been uncovered that disclose certain combinations of Lewis acid and Lewis base undergo single electron transfer (SET) processes. Here a single electron can be transferred from the Lewis basic donor to a Lewis acid acceptor to produce a reactive frustrated radical pair (FRP). This review aims to highlight the recent advancements in this emerging field covering the synthesis and reactivities of frustrated radical pairs, with extensive highlights of Electron Paramagnetic Resonance (EPR) data to explain the nature and stability of the radical species.
