Atomic-level insights in optimizing reaction paths for hydroformylation reaction over Rh/CoO single-atom catalyst

Nature Communications, 2016
Despite the advantages of using heterogeneous catalysts, most successful rhodium hydrogenations are carried out with homogeneous catalysts. Here the authors report a supported single atom rhodium catalyst providing high activities and selectivities for ...

Operando Transmission Electron Microscopy Insights Into the Evolution of Cu2O–SnO2‐Based Catalysts During CO2RR

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Proper CO2 management holds a key role in the energy transition, and electrochemical CO2 reduction to CO plays pivotal role in this process. Cu2O–SnO2‐based electrocatalyst is studied under electrochemical operative conditions, combining lab‐scale and operando liquid‐phase electrochemical transmission electron microscopy.

Comparison of Antibacterial Activity of Natural and Hydroformylated Essential Oil of Growing Wild in North Sardinia with Commercial Essential Oils

Natural Product Communications, 2010
Thymus capitatus growing wild in Sardinia showed different essential oil composition if grown surrounding Cagliari than in north Sardinia. Here we verify the composition and antimicrobial activity of the oil to make it suitable for the cosmetic and ...

A domino reaction for generating β-aryl aldehydes from alkynes by substrate recognition catalysis

Nature Communications, 2019
Supramolecular interactions may be responsible for higher degree of efficiency and selectivity in homogeneous catalysis. Here, the authors exploit the concept of supramolecular catalysis to develop a domino rhodium-catalyzed hydroformylation of α ...

Asymmetric Olefines Hydroformylation III: Asymmetric Induction by Rhodium Complexes Using (—)-2,3-O-Isopropylidene- 2,3-Dihydroxy-1,4-Bis(Diphenylphosphino)Butane as Chiral Ligand

CHIMIA, 1973
RhH(CO)(PPh3)3 in the presence of (—)-DIOP promotes asymmetric hydroformylation of aromatic olefines at atmospheric pressure and low temperature ; the asymmetric induction reaches in the case of styrene 25%.  DIOP: abbreviation for 2,3-O-isopropylidene-

Bio-inspired creation of heterogeneous reaction vessels via polymerization of supramolecular ion pair

Nature Communications, 2019
Tuning the environment of catalytic active sites may improve the selectivity of heterogeneous catalysts. Here, the authors modify the outer-sphere environment of active sites in hydroformylation catalysts by encapsulating the active sites in nanovessels ...

Phosphinocyclodextrins as confining units for catalytic metal centres. Applications to carbon–carbon bond forming reactions

Beilstein Journal of Organic Chemistry, 2014
The capacity of two cavity-shaped ligands, HUGPHOS-1 and HUGPHOS-2, to generate exclusively singly phosphorus-ligated complexes, in which the cyclodextrin cavity tightly wraps around the metal centre, was explored with a number of late transition metal ...
