A visible-light-induced cascade cyclization of isocyanobiaryls with hydrosilanes has been developed for the synthesis of 6-silylated phenanthridines. Readily available hydrosilanes were employed as silyl radical precursors under room-temperature conditions. The merits of the transformation include operational simplicity, mild conditions, high atom economy, and good functional group compatibility.
