    • Reaction with furan at -30°C gave no additional α product 7b, suggesting that the -10°C conditions give kinetic products.

    • In particular, the kinetic γ-:α-ratio for 1,3,5,-trimethoxybenzene (N=3.40) can be no greater than 70:30, so that it likely does not fit the exact trend of the other entries of Table 5.
