    • Experimental Procedure for the Homocoupling Reaction of 1 To a 50 mL Schlenk tube equipped with a magnetic stirring bar were added PdCl 2 (PhCN)2 (5.8 mg, 0.015 mmol, DMSO (3 mL, benzofuran (1, 55 μL, 0.5 mmol, and AgF (127 mg, 1.0 mmol) in one portion, and the resulting mixture was stirred at r.t. for 3 h. Additional AgF (2 x 1.0 mmol) were then added, and stirring was continued for further 3 h and 5 h, respectively. The reaction mixture was passed through a Celite pad to remove a solid residue, and the cake was washed repeatedly with Et2O. The filtrate was washed with H2O twice (2 x 50 mL) and brine (50 mL, Then, the organic layer was dried over anhyd MgSO4 and concentrated under reduced pressure to leave a crude solid, which was purified by chromatography on silica gel to afford 33 mg of 2 (56, 2,2′-Bibenzofuran (2)11 Mp 202-203°C. 1H NMR 500 MHz, CDCl3
