Table 2. Scope of quinolines in the Ir-catalyzed 1,2-hydrosilylation ^a .

^aSubstrate (0.35 mmol), Et₂SiH₂ (1.5 equiv.), and [Ir(coe)₂Cl]₂ (0.005 mmol, 1.4 mol%) in C₆D₆ (0.35 mL) at 55 °C; crude ¹H NMR yields based on an internal standard (mesitylene or 1,4-dioxane); numbers in parentheses are isolated yields.

^bWith 5 equiv. of Et₂SiH₂ (neat).
