Cobalt Diazo‐Compounds: From Nitrilimide to Isocyanoamide via a Diazomethanediide Fleeting Intermediate

چکیده
Lithium trimethylsilyldiazomethanide and a cobalt (II) precursor with an N-anchored tris-NHC (TIMENmes ) ligand provide access to the nitrilimide 1. Complex 1 was structurally characterized by single-crystal X-ray diffractometry (SC-XRD) its electronic structure examined in detail, including EPR spectroscopy, SQUID magnetometry computational analyses. The desilylation of C-(trimethylsilyl)nitrilimide reveals transient complex elusive diazomethanediide ligand, which substitutes one mesitylene rings ancillary through C-N bond cleavage. This transformation results cyclometalated cobalt(II) 2, featuring rare isocyanoamido-κ-C ligand.

15 صفحه اولTriplet carbenes: From fleeting existence to attractive molecular units*
Attempts to stabilize the triplet state of carbenes to the extent that they can survive under normal conditions were made, in which triplet carbenes having a half-life of 19 min are realized. A way to use the resulting persistent carbene as a unit to construct photosensitive magnetic materials is also discussed.
متن کاملFrom Conceptual Model to Oo Database via Intermediate Speciication
When designing underlying databases of information systems, data are rst modelled on conceptual level and then the obtained conceptual data model is transformed to a database. The focus of this paper is the transformation of conceptual models into object-oriented database systems. For a conceptual schema, consisting of an information structure and a set of integrity constraints , both the struc...
متن کاملElectrocatalytic water oxidation by a molecular cobalt complex through a high valent cobalt oxo intermediate.
Biuret-modified tetraamidomacrocyclic cobalt complex [CoIII-bTAML]- is shown to catalyze electrochemical water oxidation at basic pH leading to the formation of O2. Electrochemical and spectroscopic studies indicate a high valent cobalt oxo intermediate isoelectronic to CoV(O) as the active oxidant. The kinetic isotope effect of 8.63 indicates an atom proton transfer mechanism.
