Dirhodium tetraacetate

Description:

Dirhodium tetraacetate, with the CAS number 15956-28-2, is a coordination compound featuring two rhodium (Rh) metal centers coordinated to four acetate (CH3COO−) ligands. This compound is notable for its use in catalysis, particularly in organic reactions such as cyclopropanation and C-H activation. Dirhodium tetraacetate is characterized by its ability to facilitate the formation of carbon-carbon bonds, making it valuable in synthetic organic chemistry. The compound typically appears as a solid and is soluble in organic solvents. Its structure is defined by a rhodium-rhodium bond, which is relatively rare among transition metal complexes, and the acetate ligands provide a bidentate coordination mode, stabilizing the metal centers. The compound is generally handled with care due to its potential reactivity and the need for appropriate safety measures when working with metal complexes. Overall, dirhodium tetraacetate is an important reagent in the field of catalysis, contributing to advancements in synthetic methodologies.
