Abstract
A metal-free, photocatalyst-free, photochemical system enables a direct alkylation of thiophenols via electron donor-acceptor complexes between N-hydroxyphthalimide esters as acceptors and thiophenol anions as donors in the presence of a tertiary amine. The EDA complexes in the reaction system have a broad range of visible-light absorption and can trigger the reaction effectively under sunlight.
