Heavier tetrylenes (HTs), which are the heavier analogues of carbenes, have been used as ligands in transition metal chemistry for more than 50 years. Having mind that cyclometallation is a valuable tool to modify ligand scaffolds, with important implications inorganic and organic chemistry, this microreview discusses detail reactions afforded complexes cyclometallated HTs. To date, eight HT li...

E SR has been used in the study of iron(I)-nitrosyl complexes w ith organic ligands in solution. Four types of complexes have been identified on basis of the ESR param eters, namely Fe (NO) L 5, Fe (NO) L 2, Fe (NO)2L 2, and Fe (NO)2L. In the iron-nitrosyl complexes with the organic ligands used, the groups more often involved in the coordination are: —C —N H 2; —C —N H ; — C = 0 ; and —C = S (...

The search for the novel metal-organic frameworks (MOFs) materials using tetra-hydro-furan-2,3,4,5-tetra-carboxylic acid (THFTCA) as a versatile multi-carboxyl ligand, lead to the synthesis and the structure determination of the title compound, [Na(H(3)THFTCA)] or [Na(C(8)H(7)O(9))](n), which was obtained by a solution reaction at room temperature. The ligand is mono-deprotonated, coordinating ...

In soil environments, sorption/desorption reactions as well as chemical complexation with inorganic and organic ligands and redox reactions, both biotic and abiotic, are of great importance in controlling their bioavailability, leaching and toxicity. These reactions are affected by many factors such as pH, nature of the sorbents, presence and concentration of organic and inorganic ligands, incl...

At present the processes of chemical vapour deposition (MO CVD) and physical vapour deposition (PVD) are widely used to obtain the layers of different materials. A possibility to obtain materials of the required composition (elementary, complex, composite, etc.) is determined by the chemical nature of a precursor. By now a set of criteria for the precursors to meet the MO CVD and PVD standards ...

Metal-organic frameworks (MOFs) are emerging class of ordered porous materials consisting metal clusters and organic ligands. High porosity, adjustable topology, composition structural diversity have earned MOFs extensive popularity in various fields, including biosensing. This review focuses on understanding the role biosensing, mainly as efficient signal probes, nanozymes nanocarriers. It als...

Biotransformation of various chemical forms of uranium present in wastes, contaminated soils and materials by microorganisms under different process conditions such as aerobic and anaerobic (denitrifying, iron-reducing, fermentative, and sulfate-reducing) conditions will affect the solubility, bioavailability, and mobility of uranium in the natural environment. Fundamental understanding of the ...

We reported a universal route for synthesizing porous organic ligands (POLs) via solvothermal polymerization. The POLs were obtained quantitatively, showing high surface area, large pore volume, hierarchical porosity, and superior stability. The POL bearing a triphenylphosphine supported rhodium catalyst (Rh/POL-PPh3) exhibits high activity and excellent recyclability in 1-octene hydroformylation.

The syntheses of trineophyl(1a) and tri-(-)-menthylstannyl phenylacetylene (1b) as well as that of (E)-1-trineophylestannyl-2-phenylethene (2) and (E)-1-trineophylstannyl1,2-diphenylethene (3) are described. The hydrostannation of 1a with an excess of trimethyltin hydride led to 1,1,1-tris(trimethyltin)-2-phenylethane (4) and/or 1,1-bis(trimethyltin)2-phenylethene (5) depending on the reaction ...
