Rh(I) Complexes in Catalysis: a Five-Year Trend
molecules Review Rh(I) Complexes in Catalysis: A Five-Year Trend Serenella Medici * , Massimiliano Peana * , Alessio Pelucelli and Maria Antonietta Zoroddu Department of Chemistry and Pharmacy, University of Sassari, Vienna 2, 07100 Sassari, Italy; [email protected] (A.P.); [email protected] (M.A.Z.) * Correspondence: [email protected] (S.M.); [email protected] (M.P.) Abstract: Rhodium is one of the most used metals in catalysis both in laboratory reactions and industrial processes. Despite the extensive exploration on “classical” ligands carried out during the past decades in the field of rhodium-catalyzed reactions, such as phosphines, and other com- mon types of ligands including N-heterocyclic carbenes, ferrocenes, cyclopentadienyl anion and pentamethylcyclopentadienyl derivatives, etc., there is still lively research activity on this topic, with considerable efforts being made toward the synthesis of new preformed rhodium catalysts that can be both efficient and selective. Although the “golden age” of homogeneous catalysis might seem over, there is still plenty of room for improvement, especially from the point of view of a more sustainable chemistry. In this review, temporally restricted to the analysis of literature during the past five years (2015–2020), the latest findings and trends in the synthesis and applications of Rh(I) complexes to catalysis will be presented. From the analysis of the most recent literature, it seems clear that rhodium-catalyzed processes still represent a stimulating challenge for the metalloorganic chemist that is far from being over.

Delmas b a Chemical Engineering Division, National Chemical Laboratory, Pune 411008, India b Universite´ de Toulouse, Laboratoire de Ge´nie Chimique, UMR 5503 CNRS/ENSIACET, Toulouse, France a b s t r a c t Biphasic hydroformylation of 1-octene was performed using rhodium sulfoxantphos catalyst dissolved in [BuPy][BF4] ionic liquid. Preliminary experiments proved this system to retain the catalytic complex within the ionic liquid phase and to maintain a high selectivity towards the linear aldehyde (n:iso ratio of 30) over several cycles. Process parameter investigation showed a first order dependence of the initial rate with respect to the catalyst and 1-octene concentrations, but a more complex behavior with respect to hydrogen (fractional order) and carbon monoxide partial pressures (inhibition at high pressures). -

Hydrogenation of Small Aromatic Heterocycles at Low Temperatures

Miksch,1 Annalena Riffelt,1 Ricardo Oliveira,2 Johannes Kästner,1 and Germán Molpeceres,1¢ 1Institute for Theoretical Chemistry, University of Stuttgart, Stuttgart, Germany 2Chemistry Institute, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil Accepted XXX. Received YYY; in original form ZZZ ABSTRACT The recent wave of detections of interstellar aromatic molecules has sparked interest in the chemical behavior of aromatic molecules under astrophysical conditions. In most cases, these detections have been made through chemically related molecules, called proxies, that implicitly indicate the presence of a parent molecule. In this study, we present the results of the theoretical evaluation of the hydrogenation reactions of different aromatic molecules (benzene, pyridine, pyrrole, furan, thiophene, silaben- zene, and phosphorine). The viability of these reactions allows us to evaluate the resilience of these molecules to the most important reducing agent in the interstellar medium, the hydrogen atom (H). All significant reactions are exothermic and most of them present activation barriers, which are, in several cases, overcome by quantum tunneling. Instanton reaction rate constants are provided between 50 K and 500 K. For the most efficiently formed radicals, a second hydrogenation step has been studied. We propose that hydrogenated derivatives of furan, pyrrole, and specially 2,3-dihydropyrrole, 2,5-dihydropyrrole, 2,3-dihydrofuran, and 2,5-dihydrofuran are promising candidates for future interstellar detections.
