TLDR
The present article outlines the most important nonenzymatic reactions of cobalt in vitamin B12 and in model compounds of the cobaloxime type.Abstract:
Studies with vitamin B12 model compounds such as the cobaloximes provide a basis for the understanding of the mode of action of corrinoid coenzymes in enzymatic reactions. They also widen our knowledge of the properties and reactions of organocobalt compounds. The present article outlines the most important nonenzymatic reactions of cobalt in vitamin B12 and in model compounds of the cobaloxime type.read more

Homo- and hetero-polymetallic exchange coupled metal-oximates
TL;DR: In this paper, the authors focused on such exchange coupled polymetallic, both homo- and hetero-metallic systems containing the bridging core MNOM′ with an aim to delineate the exchange mechanism through bridging oximates, and confirmed the essentially σ nature of the exchange interaction transmitted through the diatomic NO-bridging ligand.

Metal-ion assisted reactions of oximes and reactivity of oxime-containing metal complexes
TL;DR: A review of metal-ion assisted reactions of oximes and reactivity of oxime-containing metal complexes has been presented in this paper, where the authors made an attempt to show general features of some reactions and to systematize reaction types.

Mechanistic insights into the cobalt-mediated radical polymerization (CMRP) of vinyl acetate with cobalt(III) adducts as initiators.
TL;DR: Two mechanisms are shown to coexist: the reversible termination of the growing poly(vinyl acetate) chains by the Co(acac)2 complex (acac: acetylacetonato), and a degenerative chain-transfer process.
