    • A cation effect may also be responsible. Addition of LiHMDS in DAG sulfinate esters is stereospecific, but NaHMDS proceeds with considerable racemization. Kim, K.; Backes, B. J.; Ellman, J. A., unpublished results.

    • note
    • To attain the optimal interface surface area, the crystallizing dish described here was effective. For 0.5-mol-scale oxidations of disulfide 1, a simple 500-mL Erlenmeyer flask provided the best interface area. Stirring was always performed with a magnetic stir bar; overhead mechanical stirrers break the organic-aqueous interface.
