摘要：
Comparison of the thermodynamic (logK(HB) with 4-fluorophenol in CCl4 pK(a) in azeotropic ethanol and GB in the gas phase) with spectroscopic basicities (Delta v(OH) of methanol in CCl4) for N-1,N-1-dimethylformamidines shows good correlation only between the pK(a) and Delta v(OH) values; mo general simple linear model can be applied to the logK(HB)/Delta v(OH) and GB/Delta v(OH) relations.
