New Wind in Old Sails: Novel Applications of Triphos-based Transition Metal Complexes as Homogeneous Catalysts for Small Molecules and Renewables Activation

Recent developments in the coordination chemistry and applications of Ru-triphos [triphos = 1,1,1-tris-(diphenylphosphinomethyl)ethane] systems are reviewed, highlighting their role as active and selective homogenous catalysts for small molecule activation, biomass conversions and in carbon dioxide utilization-related processes

Phosphorus Coordination Chemistry: A Special Issue in Honor of Maurizio Peruzzini.

The present Article Collection celebrates the outstanding scientific career of Maurizio Peruzzini and his interest in Phosphorus Chemistry. Maurizio was formed as a young chemist at the University of Florence (Italy) under the supervision of Piero Stoppioni and Claudio Bianchini, thus belonging to the numerous heirs of the prestigious chemistry school of Luigi Sacconi. After a period as research assistant at the same University, in 1986 he won a place as researcher at CNR-ISSECC, now CNR-ICCOM, where Maurizio spent most of his further activity as scientist. Since the beginning, he got fascinated by the beauty and complexity of main group and transition metal coordination chemistry, in particular phosphorus in all its allotropic forms. This interest accompanied him throughout his scientific career, that saw promotions first to Senior Researcher (1996–2001) and then to Research Director (2001– 2020). In 2013 he became Director of CNR-ICCOM, after two years as Deputy Director, and in 2017 he took the position of Director of the CNR Department of Chemical Sciences and Materials Technology in Rome, until retirement in 2020. Since then, Maurizio has taken the role of Senior Associate at CNR-ICCOM, and still actively collaborates with his coworkers in various fields of research. His commitment to the development of chemistry in Italy brought him to become President of the Inorganic Chemistry Division of the Italian Chemical Society (2009–2011). He was the mentor of many undergraduate, postgraduate students and postdoctoral fellows coming from all over the world to join his research group in Florence. Maurizio’s bibliometric data are truly outstanding, with more than 400 co-authored peer-reviewed papers, more than 13,000 citations and an h-index of 57 (WoS data, 14th April 2021)

The EPSRC doctoral training grant supported RP (DTG grant: 1518070)). The EPSRC (EP/M003868/1) is also acknowledged for funding (JAF&PD).The scope of carbon monoxide-free Asymmetric Transfer HydroFormylation (ATHF) procedures using a highly active single catalyst system derived from 1,2-bis-((2,5)-diphenylphospholano)ethane as chiral ligand has been studied. This reveals some highly successful reactions, but also significant limitations. The development of a new protocol in which a catalyst for formaldehyde decomposition to CO and H2 is combined with the catalyst of choice for the subsequent asymmetric hydroformylation is described. This enables ATHF reactions that were problematic to be significantly improved. The new method has been used in the synthesis of several key precursors to biologically active molecules.PostprintPeer reviewe

High iso aldehyde selectivity in the hydroformylation of short-chain alkenes

The authors thank the Eastman Chemical Company for funding (LI, and later JAF) and permission to publish. The EPSRC (EP/M003868/1) is also acknowledged for funding (JAF).The hydroformylation of propene to give predominantly iso‐butanal has been achieved; class‐leading selectivity is possible even at higher temperatures that deliver fast conversion. Racemic rhodium complexes of bidentate phospholane phosphites derived from tropos‐biphenols and unusual solvent systems are the key to the selectivity observed.PostprintPeer reviewe
