A bimetallic [Ir3+]2 complex was synthesized based on a bridging 1,2,3-triazole ligand that coordinates to one Cp*Ir unit as N,N-bidentate chelate, and to the other as a C,C-bidentate ligand. When compared to monometallic homologues, the bimetallic complex shows greatly enhanced product selectivity for the acceptorless dehydrogenation of alcohols; spectroscopic and electrochemical analysis suggest significant alteration of the metal properties in the bimetallic system compared to the monometallic species, which offers a rationale for the observed high selectivity.
- We have synthesized suitable ligands and their iridium complexes, and have identified and assessed their bifunctional reactivity.
- The catalytic activity of this bifunctional catalyst has been investigated and evaluated in amine dehydrogenation and in the acceptor-free alcohol dehydrogenation catalysis.
- Stoichiometric experiments with the catalyst precursor were carried out allowing us to understand the mechanistic details. That will help us to design further modifications for catalyst improvement.
