General Information. Ethyl acetate (ACS grade), hexanes (ACS grade) and

anhydrous 1, 2-dichloroethane (ACS grade) were obtained commercially and used

without further purification. Methylene chloride, tetrahydrofuran and diethyl ether were

purified according to standard methods unless otherwise noted. Commercially available

reagents were used without further purification. Reactions were monitored by thin layer

chromatography (TLC) using silicycle pre-coated silica gel plates. Flash column

chromatography was performed over silica gel (300-400 mesh). Infrared spectra were

recorded on a Nicolet AVATER FTIR330 spectrometer as thin film and are reported in

reciprocal centimeter (cm-1). Mass spectra were recorded with Micromass QTOF2

Quadrupole/Time-of-Flight Tandem mass spectrometer using electron spray ionization. 1H NMR spectra were recorded on a Bruker AV-400 spectrometer and a Bruker AV-

500 spectrometer in chloroform-d3. Chemical shifts are reported in ppm with the internal

TMS signal at 0.0 ppm as a standard. The data is being reported as (s = singlet, d =

doublet, t = triplet, m = multiplet or unresolved, brs = broad singlet, coupling constant(s)

in Hz, integration). 13C NMR spectra were recorded on on a Bruker AV-400 spectrometer and a Bruker

AV-500 spectrometer in chloroform-d3. Chemical shifts are reported in ppm with the

internal chloroform signal at 77.0 ppm as a standard.

HNTf2 (3.0 mL, 0.05 M in DCE), and [(C6F5)3PAuNTf2] (15.1 mg, 0.015 mmol) were

added to a solution of the o-propargylbiaryls 1 (0.30 mmol) in DCE (3.0 mL) at room

temperature. The reaction mixture was stirred at room temperature and the progress of the

reaction was monitored by TLC. The reaction typically took 5 h. Upon completion, the

reaction diluted with DCM (30 mL) and washed with saturated aqueous NaHCO3 (2 × 15

mL). The resulting solution was extracted again with DCM (30 mL) and the combined

organic layers were dried with MgSO4. The mixture was then concentrated and the

residue was purified by chromatography on silica gel (eluent: hexanes/ethyl acetate) to

afford the desired products 2.
