    • note
    • 3) the isolated yields are reported. For Tables 2 and 3, yields were determined by NMR via comparison to an equimolar amount of 1,2-dimethoxyethane (based on starting phenol) added to the crude reaction mixture after reaction completion and cooling. In all cases, the term 'significant amount' indicates a cutoff of 5% relative to starting phenol.
