Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Dual‐Sabatier Optima: How Reaction Mechanism Determines Activity Volcano Map of Dual‐Atom Catalysts for Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Dual‐atom catalysts (DACs) for oxygen reduction reaction (ORR), where the dissociative mechanism dominates, show a dual‐Sabatier optima volcano map, diverging from the classical single‐peak volcano of the associative mechanism. Potential‐dependent microkinetic modeling and interpretable machine learning rationalize experimental data and provide design ...

Multi‐Objective Catalyst Discovery in High‐Entropy Alloy Composition Space: The Role of Noble Metals on the Pareto Front for Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Pareto optimal compositions of alloy catalyst for oxygen reduction reaction are uncovered through multi‐objective Bayesian optimization of activity, stability, and material cost in an eight‐element high‐entropy alloy composition space. The substantial Pareto front obtained is compared to experimental literature and analyzed to elucidate the roles and ...

Out‐of‐Equilibrium Supramolecular Assembly Sustained by Photocatalysis

Angewandte Chemie, EarlyView.
Catalysis sustains structure: A Pt(II) supramolecular photocatalyst persists in a far‐from‐equilibrium state only as long as it remains photocatalytically active. Without ongoing catalytic activity, the system irreversibly relaxes into a thermodynamically stable but inactive state (PtB). Catalysis is essential for sustaining its structure.

Ruthenium maltolato complexes

Chemical Communications, 1997
Two maltol molecules can be deprotonated and coordinated to Ru II to generate a series of octahedral complexes having the general formula Ru(ma) 2 L 2 (ma = C 6 H 5 O 3 ; L = PPh 3 , Me 2 SO; L 2 = cycloocta-1,5-diene); when L = PPh 3 , a precursor for the dimerization of phenylacetylene is obtained.

Fluorocarbon ruthenium complexes

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1969
Hexafluoroacetone and 1,1-dicyano-2,2-bis(trifluoromethyl)ethylene both displace carbon monoxide from the ruthenium(0) complex (CO)3[EtC(CH2O)3P]2Ru to form (CO)2[EtC(CH2O)3P]2Ru[(CF3)2CO] and (CO)2[EtC(CH2O)3P]2Ru[(CF3)2CC(CN)2] respectively, in which the CO ligands occupy a relative trans-configuration.

Cyclopentadienyl-ruthenium complexes

Journal of Organometallic Chemistry, 1981
Abstract Several ruthenium complexes of the CpRuX(PPh3)2 type, where X = Cl, Br, I, NCS, NCO, CN, BH4, H, D, and some of the CpRuS2CZ(PPh3) type, where Z = NR2 or OR, were obtained. The hydride CpRuH(PPh3)2 was obtained in high yield by reaction of CpRuCl(PPh3)2 with ROM (R = alkyl, M = alkali metal).

Electroluminescence in Ruthenium(II) Complexes

Journal of the American Chemical Society, 2002
We have investigated the electrochemical, spectroscopic, and electroluminescent properties of a family of diimine complexes of Ru featuring various aliphatic side chains as well as a more extended pi-conjugated system. The performance of solid-state electroluminescent devices fabricated from these complexes using indium tin oxide (ITO) and gold ...
