C-H Activation and Functionalisation
This iridium dimer is a potent catalyst for C-H activation reactions, enabling the ortho-silylation of aromatic ketones, benzaldehydes, and benzyl alcohols. It facilitates direct functionalisation of otherwise inert C-H bonds.
Cross-Coupling Reactions
It catalyses Suzuki-Miyau<wbr>ra coupling reactions and metalation-Suzuki cross-coupling procedures, essential for the synthesis of biaryl and heterobiaryl compounds. Tetraborylation reactions are also efficiently promoted.
Heterocyclic Synthesis
The compound has been employed in the preparation of heteroaryl fused indole ring systems. These derivatives have shown potential as inhibitors of the HCV NS5B polymerase.
Asymmetric Hydroboration
It is utilised in highly regio- and enantioselective asymmetric hydroboration reactions, providing a stereocontrolled route to valuable chiral boronic acid derivatives.
