    There have been interesting developments in photocatalysis in the past thirty years. Many of these novel compounds have been applied to solar cell research, light emitting diode manufacturing (LED) and initiators for free radical polymerizations. Specifically, cyclometallated ruthenium and iridium complexes are pervasive and figure prominently.  Recently, these compounds have been successfully applied to catalytic transformations. These d6 coordinatively unsaturated 18-electron species are capable of utilizing metal to ligand charge transfer states generated during excitation with visible light.  Taking advantage of oxidative and reductive pathways created by these excited state species, allows them to be applied as novel catalysts. These catalysts can also be utilized in challenging organic transformations in both bench-top and commercial scales.
