The reaction conditions: 1x (0.2 mmol), 2x (0.8 mmol), catalyst (0.01 mmol), Cu(OAc)2 (0.8 mmol) and AgNTf2 (0.02 mmol) in [BMIM]NTf2 (0.8 mL) were stirred under argon at r.t. for 24 h in a sealed tube.
Isolated yield.
The catalysts are: A ([Cp*RhCl2]2); B (Cp*Rh(OAc)2); C ([Cp*Rh(MeCN)3][SbF6]2); D ([Cp*CoCl2]2); E ([Cp*Co(MeCN)3][SbF6]2); F ([Ru(p-cymene)Cl2]2).
