12.1 QUANTUM-CHEMICAL CALCULATION OF MOLECULE 1,4-(1,1’-3,3’-DIINDENYL)BUTANE BY METHOD AB INITIO
12.1.1 INTRODUCTION
In this section, for the first time quantum chemical calculation of a molecule of 1,4-(1,1’-diindenyl)butane is executed by method AB INITIO with optimization of geometry on all parameters. The optimized geometrical and electronic structure of this compound is received. Acid power of 1,4-(1,1’-diindenyl)butane is theoretically appreciated. It is established, than it to relate to a class of very weak H-acids (pKa = +32, where pKauniversal index of acidity).
