Organotransition metal complexes capable of forming metalloradicals have been an intriguing subject of study for the past fifty years. Of these, rhodium porphyrin complexes have proven particularly interesting due to their straightforward synthesis and unique reactivity; indeed, these complexes are responsible for some highly influential transformations of organic compounds, including rare C-H and C-C bond activations. The complexity and selectivity of rhodium porphyrins has been attractive for catalytic transformations, with specific interest in their usage for selective carbon monoxide reduction for fuel cell applications. This review will highlight historical and modern syntheses of rhodium porphyrins, as well as their respective reactions with small molecules and applications therein. The discussion will be limited to rhodium porphyrins consisting of four pyrrolic rings bridged with four methine units.

Rhodium Bohr ModelThe number of electrons in each of Rhodium's shells is [2, 8, 18, 16, 1] and its electron configuration is [Kr] 4d8 5s1. The rhodium atom has a radius of 134 pm and a Van der Waals radius of 195 pm. Rhodium was discovered and first isolated by William Wollaston in 1804. In its elemental form, rhodium has a silvery white metallic appearance. Elemental RhodiumRhodium is a member of the platinum group of metals. It has a higher melting point than platinum, but a lower density. Rhodium is found in ores mixed with other metals such as palladium, silver, platinum, and gold. Rhodium is primarily used as the catalyst in the three-way catalytic converters of automobiles it is also highly valued in jewelry. The name Rhodium originates from the Greek word 'Rhodon,' which means rose.
