OPEN Repository

Welcome to OPEN - the Repository of Open Scientific Publications, run by the Interdisciplinary Centre for Mathematical and Computational Modelling, University of Warsaw, previously operating as the CeON Repository. The Repository enables Polish researchers from all fields to openly share their articles, books, conference materials, reports, doctoral theses, and other scientific texts.

Publications in the Repository are indexed by the most important search engines and aggregators and downloaded by users worldwide. We invite you to create an account, deposit your publications, and use the resources of the Repository.

Reductive Elimination from Sterically Encumbered Ni−Polypyridine Complexes

(American Chemical Society, 2022) Day, Craig S.; Ton, Stephanie J.; McGuire, Ryan T.; Foroutan-Nejad, Cina; Martin, Ruben; Barcelona Institute of Science and Technology, Institute of Chemical Research of Catalonia; Departament de Química Analítica i Química Organica, ̀ Universitat Rovira i Virgili, Spain; Institute of Organic Chemistry, Polish Academy of Sciences

Herein we disclose the synthesis of sterically encumbered dialkylnickel(II) complexes bearing 2,9-dimethyl-1,10-phenanthroline ligands. A comparison with their unsubstituted analogues by both X-ray crystallography and theoretical calculations revealed significant distortions in their molecular structures. Eyring plots along with stoichiometric and photoexcitation studies revealed that sterically encumbered dialkylnickel(II) complexes enable facile C(sp3)–C(sp3) reductive elimination, thus offering an improved understanding of Ni catalysis.
