Journal ArticleDOI
Radical Ligands Confer Nobility on Base-Metal Catalysts
Paul J. Chirik,Karl Wieghardt +1 more
TL;DR: The oxidation state of metals such as copper and iron can be stabilized by organic ligands that add or lose electrons and facilitate catalysis, and why there can be advantages to having the redox changes occur in the ligands instead.
Journal ArticleDOI
The Active Sites in Manganese-Containing Metalloproteins and Inorganic Model Complexes
TL;DR: In this paper, the structural properties of manganese metalloproteins with polynuclear active sites are described and the experimental evidence for their proposed structures are described, and a large number of such complexes have been synthesized, their X-ray structures determined and their magnetic and spectroscopic properties studied in detail.
Journal ArticleDOI
Electronic Structure of Bis(o-iminobenzosemiquinonato)metal Complexes (Cu, Ni, Pd). The Art of Establishing Physical Oxidation States in Transition-Metal Complexes Containing Radical Ligands
Phalguni Chaudhuri,Cláudio Nazari Verani,Eckhard Bill,Eberhard Bothe,Thomas Weyhermüller,Karl Wieghardt +5 more
TL;DR: The ligand 2-anilino-4,6-di-tert-butylphenol and its 2-(3,5-dichloroanilino)-4,4-dimethyl-1,4,7-triazacyclononane analogue react in CH(3)CN or CH( 3)OH solutions with divalent transition metal ions in the presence of air and triethylamine.
Journal ArticleDOI
Synthesis, crystal structures, reactivity, and magnetochemistry of a series of binuclear complexes of manganese(II), -(III), and -(IV) of biological relevance. The crystal structure of [L'MnIV(.mu.-O)3MnIVL'](PF6)2.H2O containing an unprecedented short Mn.cntdot..cntdot..cntdot.Mn distance of 2.296 .ANG.

Journal ArticleDOI
Aerobic Oxidation of Primary Alcohols (Including Methanol) by Copper(II)− and Zinc(II)−Phenoxyl Radical Catalysts
Phalguni Chaudhuri,Martina Hess,Jochen Müller,Knut Hildenbrand,Eckhard Bill,and Thomas Weyhermüller,Karl Wieghardt +6 more
TL;DR: The tetradentate ligand N,N-bis(3,5-di-tert-butyl-2-hydroxyphenyl)-1,2-phenylenediamine, H4L1, has been prepared as mentioned in this paper.
