Following reported procedure, 7 Trimethylsilyl triflate (1.0 mL, 5.5 mmol, 1.1 equiv) was added to a suspension of 2-iodosylbenzoic acid ( ) (1.3 g, 5.0 mmol, 1.0 equiv) in CH2Cl2 (15 mL) at RT The resulting suspension was stirred for 1 h, followed by the dropwise addition of (( bromophenyl)ethynyl)trimethylsilane ( ) (1.39 g, 5.5 mmol, 1.1 equiv), which was dissolved in CH2Cl2 (1 mL). The resulting suspension was stirred for 6 h at RT A saturated solution of NaHCO3 (20 mL) was then added and the mixture was stirred vigorously for 30 min, the two layers were separated and the organic layer was washed with sat. The mixture was extracted with H2O and DCM (3x20 mL), washed with brine, then dried over Na2SO4, filtered and evaporated under reduced pressure. The resulting solid was recrystalized in EtOAc:MeOH Consistent with reported data. 7
