    • Careful examination by HMQC proved that the dichloride was vicinal based on the fact that the singlet at δ, 6.21 ppm coupled to two different carbon atoms

    • Sulfuryl chloride was purchased from Aldrich, and used in many reactions with complete reproducibility. Recently, two batches from Aldrich were used in an identical manner, but required a larger excess of reagent, longer reaction times, and gave poorer yields. Aldrich simply stated that they had a different supplier, but did not elaborate. We could detect no difference in the batches by GC-MS or IR analysis
