Web12. apr 2024. · A visible-light-induced acyl radical conjugate addition to electron-deficient alkenes with acylsilane was realized by merging photoredox and Lewis acid catalysis under mild reaction conditions. Various tri- and tetra-substituted furans were obtained with good yield (up to 97%) from α,β-unsaturated ketones. WebNow universally known as the Lewis acid-base definitions, these concepts define an acid as an electron-pair acceptor and a base as an electron-pair donor. First proposed, almost as a passing thought, in his 1923 monograph on chemical bonding, discussions of Lewis acids and bases are now found in most introductory chemistry textbooks.
