Rhodium Hydroformylation and Bismuth Main-Group Catalysis
This research community develops catalysts for converting olefins into aldehydes and explores the reactivity of bismuth and phosphorus compounds in organic synthesis. The work focuses on creating efficient, selective, and recyclable systems for industrial chemical production and fundamental molecular design.
The community is defined by two distinct but related strands of catalytic chemistry. The first involves the hydroformylation of olefins, particularly ethylene and propene, using rhodium-based catalysts. Recent efforts emphasize heterogeneous systems, including single-atom sites, zeolite-anchored complexes, and supported nanoparticles, to improve selectivity and ease of separation from homogeneous Wilkinson-type catalysts. The second strand centers on main-group element chemistry, specifically the synthesis and reactivity of bismuth(III) and bismuth(II) complexes, phosphorus-containing radicals, and antimony compounds. This work investigates oxidative addition, redox catalysis, and the structural characterization of these metal-ligand frameworks to enable new synthetic transformations, such as radical coupling and photocatalytic reactions.
The largest share of the community's output is found in rhodium research, accounting for 27.0% of all rhodium research tracked, with 6,147 papers in this group. Phosphorus research contributes 4.8% of its total output, and platinum research contributes 5.7%.
The community comprises 59,875 papers, publishing primarily in the Journal of Organometallic Chemistry, Inorganic Chemistry, and the Journal of the American Chemical Society.
Recent work continues to refine heterogeneous rhodium catalysts for ethylene and hindered olefin hydroformylation, including zeolite-anchored sites and click-chemistry-derived recyclable phosphines. Simultaneously, new studies characterize bismuth radical anions, ligand-controlled bismuth catalysis for coupling reactions, and the bioactivity of bismuth-selenopeptides.
