Correlation between the rates of benzylidene condensation of R-tetrazol-1-ylphenylamines and their dissociation constants
摘要:
Benzylidene condensation of R-tetrazol-1-ylphenylamines with 4-fluorobenzaldehyde was studied. The correlation between the logarithm of the rate constant of the condensation of 4-fluorobenzaldehyde with R-tetrazol-1-ylphenylamines and their pK (BH)+ values was found. The reaction constant rho in the Hammett equation was determined.
