From: Ligand-controlled regiodivergent and enantioselective C–H cyanation of secondary amines
Condition A: 1 (0.2 mmol), Cu(CH3CN)4BF4 (3.1 mg, 5 mol%), L (12 mol%), TMSCN (59.5 mg, 0.6 mmol), DCM (4 mL), N2, rt, 0.5 h; isolated yield; the regioselectivity ratios (rr) were determined by GC-MS or HPLC. [a]All rr (2/3) < 1:20.
