TL;DR: Catecholate catwalk: Monomeric manganese(III) catecholato and manmanese(II) semiquinonato complexes as the substrate-binding model of catechl dioxygenase have been synthesized and structurally characterized.
Journal ArticleDOI
Reactivity Control of a Dinuclear Xenophilic Species, Tp#Ni–RuCp(CO)2, via Spin Crossover across a Metal-metal Bond [Tp#: Hydrotris(4-bromo-3,5-dimethylpyrazolyl)borato]
TL;DR: A high-spin, triplet xenophilic complex, Tp#Ni-RuCp(μ-CO)2, readily reacted with 2e-donors (L) via spin crossover at Ni associated with transposition of the resultant coordinatively unsaturated site from Ni to Ru to give diamagnetic adducts as discussed by the authors.
Journal ArticleDOI
Acetoxybis(imidazolyl)methylborate [B(ImN-Me)2(OC(O)Me)Me]−: Carboxylation of borane moiety of imidazolyl-based scorpionate
TL;DR: In this paper, the boron-acetoxy linkage survives upon the treatment of the nickel complexes with OH−, although the acetoxy group on LOAc does not coordinate to the nickel center.
Journal ArticleDOI
Coordination Properties of Organoborate Ligands – Steric Hindrance Around the Distal Boron Center Directs the Conformation of the Dialkylbis(imidazolyl)borate Scaffold
TL;DR: In this paper, a homoleptic complex of nickel(II) with L alkyl was presented, where the boron-attached nBu and Me groups are located away from the nickel center and the orientation of the two imidazolyl groups is almost coplanar in 2 Bu.
Journal ArticleDOI
Dichloromethane Activation by Chlorochromium(II) Complexes with TpiPr2: Generation of an Electrophilic Cr–Methylene Species without the Action of an External Cl-Abstraction Reagent
TL;DR: In this paper, five-coordinated chlorochromium(II) complexes with TpiPr2 activate CH2Cl2 to give a metal-carbene species without the action of an external Cl-abstraction reagent, and the resulting methylene fragment is trapped by nucleophiles such as pyrazole, pyridine and olefin.
