Abstract: | The pKa and
values of a series of 3(5)-azido-1,2,4-triazoles are correlated with the
I and
C constants according to the equation pK = I I + C C + pKo. The high
I values in both cases are due to the closeness of the substituent to the reaction center. The
C/ I ratio attests to different contributions of the inductive and mesomeric effects of a substituent during transmission of its effect from the 5-position to the N1 and N4 heteroatoms.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1288–1291, September, 1974. |
