This cumulative thesis deals with the application of the Borrowing Hydrogen methodology in organic synthesis. This concept combines the dehydrogenation and hydrogenation with numerous of organic transformations. Under consideration of no hydrogen loss, even by side reaction or by gas evolution, the Borrowing Hydrogen methodology can refrain from using additional hydrogen sources. Thus, the Borrowing Hydrogen methodology is an economically and environmetally attractive strategy in organic synthesis. The thesis gives an overview of the current research in the area of Borrowing Hydrogen, which expands from activation of C-C bonds to C-O bonds and finally to C-N bonds. The results of my work, reported in the publications I-IX listed are integrated and associated with state-of-the-art chemistry in this field. My ambition is to help the reader to get interested in this field and to understand these transformations. I also want to emphasize the work I have been responsible for.

Model of DNA with David Deutsch, proponent of invariant scientific explanations. The scientific method is an empirical method of knowledge acquisition which has characterized the development of science since at least the 17th century. Though there are diverse models for the scientific method available, in general there is a continuous process that includes observations about the natural world. People are naturally inquisitive, so they often come up with questions about things they see or hear, and they often develop ideas or hypotheses about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways. Although procedures vary from one field of inquiry to another, they are frequently the same from one to another.
The purpose of an experiment is to determine whether observations agree with or conflict with the predictions derived from a hypothesis. Experiments can take place anywhere from a garage to CERN’s Large Hadron Collider. As regards his method, Aristotle is recognized as the inventor of scientific method because of his refined analysis of logical implications contained in demonstrative discourse, which goes well beyond natural logic and does not owe anything to the ones who philosophized before him. A polymath, considered by some to be the father of modern scientific methodology, due to his emphasis on experimental data and reproducibility of its results. Kepler shows his keen logical sense in detailing the whole process by which he finally arrived at the true orbit. This is the greatest piece of Retroductive reasoning ever performed. According to Albert Einstein, „All knowledge of reality starts from experience and ends in it.
