* Reaction conditions: a 0.5 mmol of azide 1, 1 mmol of substrate, 5 mol% CoP2 (w.r.t. azide), 4 mL toluene, 50 °C, 18 h. b 0.6 mmol of azide 1, 15 mL of substrate, 5 mol% CoP2, 50 °C, 18 h. These different reaction conditions (a,b) gave identical results. No nitrene transfer to the solvent (toluene) was observed in any case under the applied reaction conditions.
