Reply to Comments on “Synthesis, Characterization, and Structures of Persistent Aniline Radical Cation”

Abstract

Die Identifizierung des Anilin‐Radikalkations TBA.+ (TBA=2,4,6‐tBu3C6H2NH2), über die 2012 berichtet wurde, wird in den beiden vorhergehenden Korrespondenzartikeln angezweifelt. Die Autoren der ursprünglichen Veröffentlichung haben ihre UV/Vis‐ und EPR‐Daten nochmals überprüft und insistieren, dass das TBA.+‐Radikalkation tatsächlich beständig und stabil ist. Die mögliche Kokristallisation von TBA.+ mit TBAH+ bewirkt eine Verkomplizierung der Kristallstruktur.

Metal‐Chelating N,N′‐Bis(4‐dimethylaminophenyl)acetamidinyl Radical: A New Chromophore for the Near‐Infrared Region

“…

An ew non-innocent ligand redoxs ystem, N,N'bis(4-dimethylaminophenyl)s ubstituted acetamidinato/ acetamidinyl, has been designed and described by example of structurally and spectroscopically characterized ruthenium complexes.T he hitherto unreported ligand is responsible for rather intense and narrow absorptions in the near-infrared regiono ft he one-and two-electron oxidized forms. The spectroscopic,c omputational, and first structural characterization of an amidinyl radical complex adds to the list of established N-based radical ligands.Nitrogen-containing radicals continue to be intensely investigated and sometimes controversially discussed [1] species with applicationsi nc hemical reactivity [2] and materials science. [3] Their stability may be enhanced by metal coordination [2,[4][5][6][7] althoughtheir frequently encountered potential as non-innocent ligands [8] may occasionally give rise to false conclusions.
