Pyrazole is a tautomeric substance: in Pyrazole itself, the presence of tautomerism cannot be shown but can be inferred by considering pyrazole derivatives. Pyrazole exhibits aromatic properties, e.g., readily halogenated, nitrated and sulphonated; the group enters at position 4. The following ...
The parameters thus obtained were used to evaluate the dipole moments of pyrazole and imidazole by means of the same method. The argument between theoretical and experimental values is satisfactory. The resultant π electron densities were used as a basis for discussing electrophilic substitutions and ...
In our recent works, we studied the pyrazole ring lithiations in a series of 3-tert-butylpyrazolo[5,1-c][1,2,4]triazine derivatives [[14], [15], [16], [17]]. We found that compound 1 reacted with t-BuLi [16] as well as with dilithium-ortho-carborane [18] to selectively give...
