    • note
    • The sums of bond angles for the three bonds to the carbon atom of the oxocarbenium ions derived from acetals cis-6, trans-7, and trans-8 were found to be around 345, suggesting some bond deformation caused by the benzyloxy group. In contrast, the sum of the angles was between 355 and 360 for the slower-ionizing acetals trans-5 and trans-6

    • note
    • Determination of the relative rates of ionization of all substrates at 100 C was impossible because 46 and 47 underwent solvolysis in seconds at such high temperatures
