Description | Versatile Chemistry of Phosphorus-Substituted Carboranes Professor Evamarie Hey-Hawkins - Chair in Inorganic Chemistry, Leipzig University, Germany Host: Alexandra Velian Carboranyl derivatives with phosphorus-based substituents (phosphines, phosphites, phosphonates, etc.) can be employed as (chiral) ligands in catalysis or in medical areas. This presentation will focus on the synthesis and reactivity of secondary and (very) bulky tertiary carboranyl phosphines.[1] Furthermore, the carboranyl backbone allows the targeted synthesis of four- and five-membered phosphorus-containing heterocycles having endocyclic P–P bonds, which are difficult to obtain via other routes. In addition, 1,2-bisphosphanyl-substituted ortho-carboranes, the precursors for 1,2-diphosphetanes, 1,2,3-triphospholanes, 1,2,3- triphospholanides, and other carboranyl-substituted heterocycles will be discussed. The influence of the carboranyl backbone in redox reactions, ring-opening reactions, coordination chemistry, and catalysis will also be covered.
