    A single-electron transfer (SET) between tris(pentafluorophenyl)borane (B(C6F5)3) and N,N-dialkylanilines is reported, which is operative via the formation of an electron donor–acceptor (EDA) complex involving porbital interactions as a key intermediate under dark conditions or visible-light irradiation depending on the structure of the aniline derivatives. This inherent SET in the Lewis pairs initiates the generation of the corresponding α-aminoalkyl radicals and their additions to electron-deficient olefins, revealing the ability of B(C6F5)3 to act as an effective one-electron redox catalyst.

    In order to verify the transformation of radical reactivity depending on the coordination number of a boron center, some radical compounds with a boryl group were synthesized.In this process, we found the generation of Lewis radical-ion pairs via the single electron transfer between a Lewis acid and a base under photoirradiation. Although an additional condition, photoirradiation, is essential, the result indicates that the generation of boron-centered radical can be controlled by the presence and absence of a Lewis base. The finding will remove the barrier of structural limitation of Lewis pairs inducing single electron transfer and have a potential to accelerate the application to organic transformation and catalysis. In fact, we revealed the photocatalytic ability of electron-deficient borane, which could be a mile stone for catalysis of Lewis radical-ion pairs.
