We use concepts from organic chemistry to design tailor-made ligands. These designed ligands are then used to form metal complexes where the metal center is in a defined and confined environment. Principles from organometallic synthesis, classical coordination chemistry, and (sometimes) photochemistry and microwave irradiation are used for the synthesis of the metal complexes. Such a holistic approach helps us to generate target oriented metal complexes for catalysis and for inducing switchable properties. Working under an inert atmosphere helps us to detect reactive species with relevance to catalysis. Furthermore, controlled synthesis of reactive metal complexes is useful for probing (catalytic) reaction mechanisms.
