Fig. 3: Scope of the anilines.

aStandard reaction conditions: 1 (0.2 mmol), 2a (0.2 mmol), PdCl2(10 mol%), L1 (20 mol%), NaBArF4 (30 mol%), 2,5-DTBQ (1.5 equiv.), and Al2O3 (60 mg) in DCM (0.1 M) at 70 oC under N2 atmosphere for 72 h. Yields refer to isolated yields of 3. Diastereoisomer rate (d.r.) and regioselectivity rate (r.r.) were determined by 1H NMR. bRegioselective product mixture, overall isolated yield. ArF = 3,5-(CF3)2C6H3.
