Photoinduced metal-free cascade silylation/cyclization of alkynes/alkynones with hydrosilanes to access 3-silylated benzothiophenes and thioflavones.
A metal-free photocatalytic method for the synthesis of silylated thioflavones and benzothiophenes has been established through cascade silylation/cyclization of alkynes/alkynones with hydrosilanes. This transformation features mild reaction conditions, excellent functional group compatibility, and broad substrate scop...
