Substrate scope for the coupling of various electrophiles with alkyl Grignard reagents. a1 (0.34 mmol), FeCl3 (0.017 mmol), L1 (0.017 mmol), and Grignard reagent (0.4 mmol) added over ∼20 s. bDetermined by 1H NMR analysis using 1,3,5-trimethoxybenzene as internal standard. c1 mmol scale of 1a. Values in parentheses denote isolated yields after PTLC.
