结果酸 GCH2CO2R 和 GCH2CONR2 的 Me^O 中的平衡酸度，其中 G 是 Ph、PhS、CN、CH3CO、PhCO 或 9-芴基，R 是 Me、Et 或 t-Bu，通过先前描述的方法测量（表 I）。这些化合物的阴离子共轭碱在测量条件下是稳定的，如恒定的吸光度读数所示。尝试测量乙酸乙酯的酸度（G=
ResultsEquilibrium acidities in Me^ O for the acids GCH2C02R and GCH2CONR2, where G is Ph, PhS, CN, CH3CO, PhCO, or 9-fluorenyl and R is Me, Et, or t-Bu, were measured by the method described previously8 (TableI). The anion conjugate bases of these compounds are stable under the conditions of the measurements, as indicated by constant absorbance readings. Attempts to measure the acidityof ethyl acetate (G=
