    • While the majority of the addition reactions have been run on only a 0.5 mmol scale, a larger scale reaction (10 mmol scale) also proceeded smoothly even with reduced catalyst loading (5 mol , without any difficulty (94% isolated yield, which illustrates the robustness of the reaction. In-situ TR spectra analysis revealed that the reaction proceeded exclusively to give the addition product and was completed in 36 h Figure S2, Supporting Information
