Frustrated Lewis Pairs (FLPs) have been widely utilized as useful reagents and catalysts in organic synthesis. Recently, Frustrated Radical Pairs (FRPs), which refer to radical or radical ion variants of FLPs, have also emerged as promising reactive species for molecular transformations through mechanistic investigations in FLP chemistry. This article summarizes our recent findings on photo-promoted transformations of unreactive bonds and molecules utilizing intramolecular phosphine-borane FLPs, highlighting the novel reactivity and synthetic utility of the photochemically generated FRPs.
