N,N'-Dialkyl-N,N'-diaryl-1,10-phenanthroline-2,9-dicarboxamides (IV) were predicted (DFT simulation) and then proved experimentally to be efficient donor ligands with high unusual selectivity for the extraction separation of lanthanides. Distribution coefficients D lanthanide cations in two-phase aqueous solution-polar organic solvent decrease increasing Ln(3+) atomic number. The factors SFLn1/Ln2 adjacent ions found about 3.
Predicted by DFT simulation dilactams (<bold>B</bold>) are selective and efficient extractants for the separation of Eu<sup>3+</sup> Am<sup>3+</sup>.
Abstract Half‐sandwich manganese methylenephosphonium complexes [Cp(CO) 2 Mn(η ‐R PC(H)Ph)]BF 4 were obtained in high yield through a straightforward reaction sequence involving classical Fischer‐type complex and secondary phosphine as key starting materials. The addition of various nucleophiles (Nu) to these species took place regioselectively at the double‐bonded carbon center coordinated ligand R P + C(H)Ph produce corresponding chiral Mn(κ 1 PC(H)(Ph)Nu)], from which phosphines...
The prevalence of a counterintuitive carbene conformation in series piano-stool Mn(I) alkylalkoxycarbene complexes was rationalized by means DFT calculations and high-resolution XRD analysis terms stabilizing non-covalent C-H···C≡O interligand interactions.
The synthetic routes to Group 4–9 transition metal imido complexes are considered. Both common and less approaches analysed. classification of the methods for synthesis is based on way formation ligand, change in oxidation state during imidation type reagent.
Ferrocenium salts [(C 5 H ) 2 Fe]X (X = BF 4 , PF 6 ( I + · react with tertiary phosphines PR 3 (PMe PEt P n Bu PMe Ph, and PMePh in dichloromethane at room temperature to form a mixture of the corresponding ferrocenylphosphonium )FeC ]X III ), ferrocene phosphonium [HPR ]X. The same reaction was carried out an electrochemical cell as electrolysis solution phosphine oxidation potential ferrocene. Possible pathways for phosphination ferrocenium ion were studied by DFT M06‐L/6‐311++G(d,p)...
New aminoiminophosphoranate (κ2-(N,N)-(NC6H4i-Pr-p)2PPh2, NPN) complexes (NPN)Pd(PPh3)Cl, (NPN)2Pd, (NPN)Pt(η2-C2H4)Cl, and (NPN)Pt(PPh3)Cl were prepared in high yields from anionic [NPN]Li the corresponding transition metal chloride precursors. Reaction of (PhCN)2PdCl2 with aminoiminophosphorane [NPN]H afforded bis-imino complex Pd{[NPN]H}2Cl2 82% yield.

Grafting Ta(═NtBu)(CH2CMe2Ph)3 onto the surface of silica partially dehydroxylated at 300 °C leads to formation imido complex (≡SiO)2Ta(═NtBu)(CH2CMe2Ph) as a major species, which was characterized with EXAFS, 13C CP/MAS NMR, diffuse reflectance FTIR, elemental analyses, and chemical reactivity. The obtained material acts an efficient heterogeneous catalyst for various oxo/imido heterometathesis transformations: imidation ketones DMF N-sulfinylamines condensation into sulfurdiimines phenyl...

Abstract Grafting Ti(=N t Bu)(Me 2 Pyr) (py) (Me Pyr= 2,5‐dimethylpyrrolyl, py=pyridine) onto the surface of silica partially dehydroxylated at 700 °C gives well‐defined silica‐supported Ti imido complex (≡SiO)Ti(=N Pyr)(py) , which is fully characterized by IR and solid‐state NMR spectroscopy as well elemental mass balance analyses. While stoichiometric imido‐transfer reactivity typical for imides, obtained unique in that it enables catalytic transformations involving oxo intermediates. In...
Easily available carbyne complexes of manganese were used as a source fragments in an unconventional synthesis backbone-substituted diphosphinomethanes and cyclic P-ylides upon coupling with secondary or tertiary phosphines, respectively, followed by demetalation under mild conditions.
