Equilibrium acidities in Me2S0 are reported for six ketimines of the type Ph2C=NCH(R)C02Et and five aldimines, ArCH=NCH(R)C02Et. Changing R in the ketimine from H to Ph increased the pKa by 2.2 units. This surprising acidity decrease for Ph substitut

The rate constants for reactions of a family of 19 carbanions, ArCHSO2Ph− (derived from benzyl phenyl sulfones) with n-butyl chloride have been measured in Me2SO solution. A plot of log k vs. the pKa of the conjugate acids for 12 of these carbanion
