CO Oxidation by N2O Homogeneously Catalyzed by Ruthenium Hydride Pincer Complexes Indicating a New Mechanism

Article abstract of DOI:10.1021/jacs.8b03927

Both CO and N₂O are important, environmentally harmful industrial gases. The reaction of CO and N₂O to produce CO₂ and N₂ has stimulated much research interest aimed at degradation of these two gases in a single step. Herein, we report an efficient CO oxidation by N₂O catalyzed by a (PNN)Ru-H pincer complex under mild conditions, even with no added base. The reaction is proposed to proceed through a sequence of O-atom transfer (OAT) from N₂O to the Ru-H bond to form a Ru-OH intermediate, followed by intramolecular OH attack on an adjacent CO ligand, forming CO₂ and N₂. Thus, the Ru-H bond of the catalyst plays a central role in facilitating the OAT from N₂O to CO, providing an efficient and novel protocol for CO oxidation.

Just Accepted
“Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted
online prior to technical editing, formatting for publication and author proofing. The American Chemical
Society provides “Just Accepted” as a service to the research community to expedite the dissemination
of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in
full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully
peer reviewed, but should not be considered the official version of record. They are citable by the
Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore,
the “Just Accepted” Web site may not include all articles that will be published in the journal. After
a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web
site and published as an ASAP article. Note that technical editing may introduce minor changes
to the manuscript text and/or graphics which could affect content, and all legal disclaimers and
ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or
consequences arising from the use of information contained in these “Just Accepted” manuscripts.
