    • General Procedure To an 100 mL autoclave, phenylacetylene (3.0 mmol, iodobenzene (2.0 mmol, Cu(TMHD)2 (0.1 mmol, toluene (10 mL) and Et3N (6.0 mmol) were added. The mixture was first stirred for 10 min, then the vessel pressures 8-20 atm of CO and the reaction mixture was heated at 90°C for 14 h. After the reaction was complete, the mixture was extracted with EtOAc (3 x 10 mL, the combined organic extracts were dried over Na2SO4, and the solvent was removed under vacuum. The residue obtained was purified by column chromatography (silica gel, 60-120 mesh) using PE (60:80)-EtOAc as eluent to afford the pure products. All the compounds are known and were characterized by GC-MS (Shimadzu) and NMR (Varian 300 MHz, Spectroscopic Data of Representative Compounds Table 2, Entry 1: GC-MS: m/z, 206 [M, 178, 129 (100, 1H NMR (300 MHz, CDCl3, 25°C, δ, 749-7.54 m, 5 H, 7
