AB  - The first chapter of this thesis describes the attempt to develop a general method for the formation of tetra-aryl substituted hydrazines, which was unsuccessful and a 5,10-diphenyl-dihydrophenazine was formed instead under the developed conditions. The generated 5,10-diphenyl-dihydrophenazine derivative was synthetized for the very first time. The second chapter of the thesis deals with the ortho-alkylation of phenols and diarylamines. The method was first optimized for tert-butyl-phenol and the scope was examined for phenols and some phenothiazines.The catalytic system used either AgBF4 or HBF4 * Et2O. Additionally, the synthetic utility was evaluated, and mechanistic experiments were conducted. In the last chapter, a one step synthesis for indoles starting from nitrobenzenes has been developed. The reaction utilizes a two-metal combination of elemental Zn as reductant and [RhCp*Cl2]2 as catalyst. The scope was investigated thoroughly, and mechanistic experiments were carried out. However due to the complexity of the reaction, the mechanistic experiments were not conclusive.
