Ruthenium-Catalyzed C–H Alkynylation of Aromatic Amides with Hypervalent Iodine–Alkyne Reagents
, 2016 An efficient C–H activation method for the ortho alkynylation of aromatic N-methoxyamides with hypervalent iodine–alkyne reagent using a ruthenium catalyst is described. The reaction proceeds under mild reaction conditions with broad substrate scope.

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Ruthenium-Mediated Regio- and Stereoselective Alkenylation of Pyridine
, 2016 A novel alkenylation reaction of pyridine is developed. Heating a cationic ruthenium vinylidene complex [CpRu(CCHR)(PPh3)2]PF6 in pyridine at 100−125 °C for 24 h affords (E)-2-alkenylpyridine.

Ruthenium-Catalyzed Transformation of Ethylene Glycol for Selective Hydrogen Gas Production in Water
, 2023 We developed an efficient process for producing hydrogen gas from aqueous ethylene glycol (EG) at 90–160 °C over a ruthenium catalyst. We achieved a high yield of hydrogen gas (up to 3.0 n(H2)/n(EG)) and formic acid (85% yield) from ethylene glycol in ...

Tin, The Enabler—Hydrogen Diffusion into Ruthenium
Nanomaterials, 2019 Hydrogen interaction with ruthenium is of particular importance for the ruthenium-capped multilayer reflectors used in extreme ultraviolet (EUV) lithography. Hydrogen causes blistering, which leads to a loss of reflectivity. This problem is aggravated by

Ruthenium-Catalyzed Intramolecular Double Hydroalkoxylation of Internal Alkynes
, 2018 Intramolecular double hydroalkoxylation of internal alkynes could be achieved using a Grubbs-type ruthenium carbene complex or its modified species to deliver a series of bridged- and spiroacetal derivatives in moderate to good yields.
