    • note
    • The polytungstate was effective for 50 cycles under the present conditions. Doubling the amount of polytungstate in the synthesis of 3bk led to only a small increase of the yield (44% with respect to 35%) whereas the yields dropped to 20.5% when using 0.2 M (in the place of 0.1 M) olefin.
