    • 11 used a 1.5/1 ratio of p-toluenesulfinate/epoxide in their studies, presumably to avoid problems associated with the rapid hydrolysis of the epoxide during the latter stages of their reactions (pH 14). Since we needed to employ valuable sulfinate salts and inexpensive epoxides in future studies, we employed a 1/1.37 ratio of sulfinate/epoxide. This also allowed direct comparison with our studies using Zn sulfinates (see Section 2).

    • Interestingly, Zn methanesulfinate and Zn butanesulfinate did not precipitate from the reaction mixture unless water was added. They were isolated as the corresponding dihydrates 9a and 9b. In contrast, Zn phenylmethanesulfinate and Zn p-toluenesulfinate precipitated directly from the ethanol solution. The precipitates contained some solvating ethanol, which was substituted by water on drying in air to produce the corresponding dihydrates 9c and 9d.
