Abstract: Catalysis is one of the cornerstones of modern chemistry. It allows difficult transformations to take place in an efficient and selective manner, making possible the design of shorter synthetic pathways and saving the chemical industry time and money. Thus, the improvement of catalysis is of great importance. In the past decades, most efforts have been oriented toward the use of second and third row transition metals, an approach that has been very successful. However, the maturity of that subfield and the improvement of characterization and modelization techniques have been leading academic researchers in exploring catalysis with other elements of the periodic table. This thesis explores metal-free catalysis, or as we like to call it metal-free organometallic chemistry. It presents advances in frustrated Lewis pair (FLP) chemistry, which uses molecules containing Lewis basic and Lewis acidic functions to access transformations that would not be possible using only one or the other. The focus of the work is mostly on understanding and exploiting FLP chemistry. Thus, we did not limit ourselves to some sub-class of FLP nor to only one transformation. The subjects contained in the thesis are quite diverse and include CO2 reduction, C-H bond functionalization, B-B bond chemistry, B-S bond chemistry as well as more fundamental discussions on future FLP catalysis development.
