AB  - The understanding of certain, still unknown, aspects of the chemical bond is made possible by new theoretical tools, particularly static DFT-D or DFT methods corrected for dispersion. These methods allow accounting for, in a physically relevant way, the effects of dispersion at medium and long distance [1]. For the further assessing the accuracy of static DFT-D calculations the providing of referential experimental data was found to be essential. It has been shown that Isothermal titration calorimetry (ITC) techniques can provide reliable thermodynamic parameters of reaction (enthalpy ΔHr, Gibbs free energy ΔGr and entropy ΔSr) [2], while some recent studies showed good agreement between experimental and theoretical results [2].
The study presented here sheds some light on the thermochemistry of reactions in solution by preforming ITC experiments in chlorobenzene and static DFT-D calculations. The study points out that, in cases where solvent molecules can interact significantly with molecules of reactants, an accounting for the explicit solvation is of crucial importance for agreement between experiment and theory. The results of various kinds of organometallic reactions will be presented in some details.

AB  - The London forces [1–3], or dispersion, are omnipresent in the nature. It constitutes an important part of the energy contribution to the stabilization of the tertiary structure of peptides, other natural polymers and the spontaneous coalescence of atomic aggregates or apolar molecules. The specifi city of the force of London is that it acts at long distances and it is always attractive, and it is therefore effective intramolecularly and determines in many situations the conformational behaviour of organic molecules and organometallics as well. It plays an essential role in chiral recognition and discrimination processes.
The understanding of certain still unknown aspects of the chemical bond is made possible by new theoretical tools, particularly static DFT-D or DFT methods corrected for Dispersion. These allow to account for in a physically relevant way the effects of dispersion at medium and long distance [4]. For the further assessing the accuracy of static DFT-D calculations providing a referential of experimental data was found essential.
It has been shown that ITC techniques can provide reliable reaction enthalpy ΔHr, Gibbs free energy of reaction ΔGr and reaction entropy ΔSr as well [5]. Some recent studies showed good agreement between experimental and theoretical results [6–8]. This study will shed some light on the thermochemistry of the reactions in solution by preforming ITC experiments in chlorobenzene, from one side, and static DFT-D calculations at different levels of theory, from another side (Fig. 1). By comparison of obtained results one could conclude on the
excellent agreement between experimental and theoretical data, which could be promising for the further development and application of static DFT-D computational methods. As examples, the results of various organometallic reactions will be presented in some details [9].
