Synthesis of phenyl biphenyl-4-carboxylate

A clean and dry 50 mL autoclave was charged with 4-iodobiphenyl (583 mg, 2.5 mmol), phenol (282 mg, 3.0 mmol), DBU (456 mg, 3.0 mmol), catalyst (1) (6.0 mg, 0.009 mmol) and benzene (5 mL), the autoclave was flushed with nitrogen three times and flushed with carbon monoxide two times, then pressurised with carbon monoxide(0.5 MPa). 

Warning extreme care should be taken (e.g. operating under excellently ventilated conditions) when handling carbon monoxide throughout the reaction run
