The indium triiodide catalyzed single-stage cascade reaction of N-sulfonyl amides with hydrosilanes and two types of organosilicon nucleophiles such as silyl cyanide and silyl enolates selectively promoted deoxygenative functionalization to give α-cyanoamines and β-aminocarbonyl compounds, respectively.
