Synthesis of Some Pyrimidine, Pyrazole, and Pyridine Derivatives and Their Reactivity Descriptors

Figure 5

Quantitative structure-reactivity descriptor relationships of the synthesized molecules and its tautomers. Each of molecules 2 and 3 has two other tautomers, while molecule 6 can exist in two tautomeric shapes (Figure 4). Similar figure is obtained in the solution phase (ACN).
