(A) General Remarks
All commercially available compounds were purchased from Sigma-Aldrich, Alfa-
Aesar, Acros, Beijing Ouhe and Beijing Chemical Works, Ltd. Unless otherwise
noted, materials obtained from commercial suppliers were used without further
purification. Analysis of crude reaction mixture was done on an Agilent 7890 GC
System with an Agilent 5975 Mass Selective Detector. Products were purified by
flash chromatography on silica gel. 1H-NMR spectra were recorded on Bruker
AVANCE III-400 spectrometers. Chemical shifts (in ppm) were referenced TMS in
CDCl3 (0 ppm). 13C-NMR spectra were obtained by using the same NMR
spectrometers and were calibrated with CDCl3 (δ = 77.00 ppm). Mass spectra were
recorded using a PE SCLEX QSTAR spectrometer. High resolution mass spectra
were obtained with a Bruker APEX IV Fourier transform ion cyclotron resonance
mass spectrometer.
(B) Experimental Procedure and Characterization Data of Products
Typical procedure for dibromination of olefins and alkynes: Olefin 1 or alkyne 6 (0.5 mmol) and DMSO (43 μL, 0.6 mmol) were dissolved in EA (2 mL). Aqueous hydrobromic acid (48%, 202 mg, 1.2 mmol) was added to the solution at 60 oC and the mixture were stirred for 0.5 h under air at that temperature. After cooling down to room temperature and concentrating in vacuum, the residue was purified by chromatography on silica gel (petroleum ether/ethyl acetate) to afford the dibrominated product 3 or 7.
