Frustrated Lewis pairs comprised of a basic yet sterically encumbered phosphine with boron Lewis acids bind nitrous oxide to give intact PNNOB linkages. The synthesis, structure, and bonding of these species are described.
Seltene Beispiele für die metallfreie Bindung von Kohlendioxid sind frustrierte Lewis‐Paare, bestehend aus sperrigen Phosphan‐ und Borankomponenten, die CO2 reversibel binden. Der Mechanismus der Bildung der CO2‐Derivate 1 und 2 durch nahezu gleichzeitige P‐C‐ und B‐O‐Bindungsbildung wurde mithilfe quantenchemischer Rechnungen charakterisiert.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
