Sunlight is regarded as the most abundant, renewable but still under-used source of energy in many practical fields including in the industrial manufacture of fine chemicals. Over the past two decades, research on visible light-mediated photoreactions has grown exponentially owing mainly to the discovery of photoredox catalysis. However, these processes are yet still very rarely used by chemical and pharmaceutical industries. To render the recent progress in fundamental photochemistry useful for societal demands, research must be focused on increasing reaction efficiency and this can only be achieved by preparing next generations of photocatalysts. RuII and IrIII complexes with polypyridine ligands are most widely used and, in many cases, can hardly be replaced. Their photocatalytic properties can be adjusted and optimized varying ligands in the coordination environment of the metal center. However, only a few available complexes are generally employed in organic synthesis due to their laborious synthesis and to the absence of any reliable guidelines for photocatalyst optimization because of a lack of systematic studies involving complexes featuring structurally and electronically tunable ligands. This work is focused on the optimization of RuII photocatalysts efficiency and has a long-term objective of developing reusable photocatalysts. Both series of Ru-P and Ru-PPh complexes prepared in this work are promising for the improvement of known photocatalytic reactions and development of novel transformations.
