cze C,N-chelatované komplexy antimonu a bismutu; oxidace a fluorace Typy překladů Přeložit text Zdrojový text The main aim of this work is a design and synthesis of hybrid systems which will contain common azobenzene function and an adjacent phosphine or phosphoramide donor group which will allow us to tune the coordination vicinity of the metal atom, prepare oligometallic species and preselect the coordination fashion. Based on our previous studies on azopyrimidines, we are aware that some troubles connected with solubility, solvent and pH sensitivity. We want to overcome such problems by employing our second expertise, phosphorus-containing compounds offering magnetically active nucleus 31P serving as a probe for reaction monitoring by 31P NMR spectroscopy. A set of organoantimony(III/V) and organobismuth(V) fluorides (i.e. L SbF2, L SbClF, LPh2SbF2, L SbF4 and LPh2BiF2) bearing the 2-{[(2,6-diisopropylphenyl)imino]methyl}phenyl-as a C,N-chelating ligand (L) has been prepared using LCNR2SnF (where LCN = 2-( N,N-dimethylaminomethyl)phenyl); R = n-Bu or Ph) and/or XeF2 as fluorinating agents. All species were characterised by the combination of elemental analy-sis and multinuclear solution NMR spectroscopy. Solid-state structures of all complexes were established by the sc-XRD analysis. In addition, theoretical calculations were carried out to corroborate the experi-mental results. Preparation and structural characterisation of LSbI2 is also reported.(c) 2023 Elsevier B.V.

L SbF2, L SbClF, LPh2SbF2, L SbF4 a LPh2BiF2) nesoucí 2-{[(2,6-diisopropylfenyl)imino]methyl}fenyl-as C,N-chelatační ligand (L) byl připraven za použití LCNR2SnF (kde LCN = 2-(N,N-dimethylaminomethyl)fenyl); R = n-Bu nebo Ph) a/nebo XeF2 jako fluorační činidla. Všechny druhy byly charakterizovány kombinací elementární analýzy a vícejaderné roztokové NMR spektroskopie.
