Abstract

New developments in computational chemistry which allow an accurate treatment of large molecules are presented. Along with a short introduction to the theoretical methods, highlights of current applications in organic chemistry are given. The so-called ‘chemical accuracy’ is now often achievable when modern methods and sophisticated techniques are applied.

1 Introduction

2 Short Review of Theoretical Methods

3 Exemplary Applications

3.1 An Instructive Example: Alkane-Branching

3.2 Relative Stability of 5-Benzylimidazolidin-4-one Derivative Conformers

3.3 Dibenzocyclic[3.2.2]nonanes: Solvent Effects on Intramolecular van der Waals Interactions

3.4 Isomerizations of Large Molecules

3.5 Relative Energies of Epimeric Carbamate Complexes for Enantiomeric Excess Prediction

3.6 Fullerenes as Dihydrogen Storage Containers: Accurate Encapsulation Energies

4 Recommended Treatments

5 Conclusion
