Reaction conditions: aAfter Co(acac)2 (4 mol%), Xantphos (4 mol%), HBdan (0.24 mmol) and NEt3 (0.6 mmol) were mixed in cyclohexane (0.2 mL, 1 M) at room temperature for 10 min, HBpin (0.3 mmol) and 1 (0.2 mmol) were added subsequently at room temperature, then the resulting mixture was stirred at ambient temperature for 12 h. b50 °C.
