Vats, Bal Govind; Gamare, Jayashree S.; Kannan, S.; Pius, I. C.; Noronha, D. M.; Kumar, M. published the artcile< Synthesis, structural and extraction studies of new bifunctional ligand with uranium>, Related Products of 5326-82-9, the main research area is crystal structure uranyl isobutylcarbamoylthio pyridyloxide; uranyl alkylcarbamoylthio pyridyloxide preparation; actinide solvent extraction alkylcarbamoylthio pyridyloxide.

A new bifunctional ligand system (N,N-dialkyl carbamoyl Me) (2-pyridyl-N-Oxide) sulfide C5H4NOSCH2CONR2, (R = isopropyl (L1), isobutyl (L2) and Bu (L3) and octyl (L4)) were synthesized. The coordination chem. of this ligand system with UO2(NO3)2·6H2O was studied. All the ligands and complexes were characterized by CHN, IR and NMR techniques. Single crystal x-ray study of 2 shows that the U atom is surrounded by eight O atoms in a hexagonal-bi-pyramidal geometry. The ligand is bonded to metal through carbamoyl and N-oxide groups in a chelating fashion. Thermogravimetric studies of the complexes shows that the ligands are completely incinerable. Extraction studies of the actinides with ligand L4 show that this new bifunctional ligand has very good distribution ratio (D) values for tetravalent and hexavalent actinides ions from HNO3 medium.

Reany, Ofer; Blair, Stephanie; Kataky, Ritu; Parker, David published the artcile< Solution complexation behavior of 1,3,5-trioxycyclohexane based ligands and their evaluation as ionophores for Group IA/IIA metal cations>, Category: amides-buliding-blocks, the main research area is metal selectivity cyclohexanetriol solution complexation ligand conformation hydrogen bond.

A new series of cis,cis-cyclohexane-1,3,5-triol derivatives bearing one, two and three carbamoylalkyl substituents is reported. Ring interconversion promoted by intramol. hydrogen bonding is observed for the mono- and di-alkylated derivatives 3 and 4 depending on solvent polarity. 1H NMR parameters obtained have allowed the calculation of the Gibbs free energy change (ΔG 0) for the trioxa-equatorial ↔ trioxa-axial equilibrium, modeling the conformational changes promoted by ion binding. Selectivity coefficients have been assessed electrochem. using fixed interference methods for the detection of biol. relevant IA/IIA metal cations. Ionophore 4 displays a Nernstian response towards the detection of Ca2+ and logKCa,Mpot values are calculated Solution NMR studies confirm the formation of 1:1 complexes for 4 with lithium, while 2:1 complexation is favored with Ca2+. Detailed ES-MS studies performed under controlled conditions revealed similar trends in ion binding.

Deb, S. B.; Gamare, J. S.; Kannan, S.; Drew, M. G. B. published the artcile< Uranyl(VI) and lanthanum(III) thio-diglycolamides complexes: Synthesis and structural studies involving nitrate complexation>, Application of C10H20ClNO, the main research area is thiodiglycolamide preparation complexation uranyl lanthanum nitrate; crystal structure uranyl lanthanum thiodiglycolamide nitrato complex; solvent extraction uranyl cation nitric acid medium thiodiglycolamide ligand.

New tri-functional ligands R2NCOCH2SCH2CONR2 (R = iso-Pr, Bu or iso-butyl) were prepared and characterized. The coordination chem. of these ligands with uranyl and lanthanum(III) nitrates was studied by using the IR, 1H NMR and elemental anal. methods. Structures for [UO2(NO3)2(iPr2NCOCH2SCH2CONiPr2)], [UO2(NO3)2(iBu2NCOCH2SCH2CONiBu2)], [La(NO3)3(iPr2NCOCH2SCH2CONiPr2)2] and [La(NO3)3(iBu2NCOCH2SCH2CONiBu2)2] were determined by single crystal x-ray diffraction. These structures show that the ligand acts as a bidentate chelating ligand and bonds through both the carbamoyl groups to the uranyl and La(III) nitrate groups. Solvent extraction studies show that the ligand can extract the uranyl ion from the HNO3 medium but does not show any ability to extract the Am(III) ion.

Sharma, Shikha; Ghosh, Sunil K.; Kumar, Mukesh; Sharma, Joti N. published the artcile< Synthesis and X-ray crystallographic characterization of two different inorganic-organic hybrid isopolyoxomolybdates with α-dipropylammonium N,N-diisobutylacetamide by varying reaction conditions>, Recommanded Product: 2-Chloro-N,N-diisobutylacetamide, the main research area is propylammonium diisobutylacetamide polyoxomolybdate complex preparation crystal structure.

Two new polyoxomolybdate based inorganic-organic hybrid compounds were obtained from same ammonium ion ligand 1 and molybdate source just by altering reaction conditions. The new hybrid polyoxomolybdate complexes (LH)2[Mo6O19] 3 and (LH)4[Mo8O26](MeCN)2 4 have distinct structural features revealed by x-ray crystallog. studies. The complex 3 contains two ammonium ligands to balance the charge on hexamolybdate dianion. The most striking feature of (LH)2[Mo6O19] is the presence of inter-ligand hydrogen bonding (N-H···O:C) between two ligands arranged in an antiparallel fashion that favors the formation of a net like structure which embeds the Mo6O19 dianion. The complex 4 contains four ammonium ligands to balance the charge on β-octamolybdate tetraanion. Complex 4 exhibits strong hydrogen-bonding interactions between ammonium ligand and octamolybdate anion (N-H···O-Mo) and no inter-ligand H-bonding interaction. The different structural features of hybrid compounds 3 and 4 suggest that different polyoxomolybdate clusters play a key role in the process of assembling of ligands.

Crowe, Matthew C.; Kapoor, Ramesh N.; Cervantes-Lee, Francisco; Parkanyi, Laszlo; Schulte, Louis; Pannell, Keith H.; Brodbelt, Jennifer S. published the artcile< Investigating Bidentate and Tridentate Carbamoylmethylphosphine Oxide Ligand Interactions with Rare-Earth Elements Using Electrospray Ionization Quadrupole Ion Trap Mass Spectrometry>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is bidentate tridentate carbamoylmethylphosphine oxide ligand extractant rare earth element.

Electrospray ionization (ESI) quadrupole ion trap mass spectrometry (QIT-MS) and collisionally activated dissociation (CAD) were used to evaluate the rare-earth binding properties of two hydrophobic carbamoylmethylphosphine oxide (CMPO) ligands, the normal bidentate variety, (t-BuC6H4)2P(O)CH2C(O)N(i-Bu)2 (A), a new potentially tridentate extractant, (t-BuC6H4)2P(O)CH[CH2C(O)N(i-Bu)2]C(O)N(i-Bu)2 (B), and tri-Bu phosphate. The mass spectral results obtained from anal. of 1% HNO3/methanol solution containing the ligands and dissolved lanthanide salts reveal that the favorable stoichiometries of the ligand/metal/nitrate complexes are 2:1:2 for the bidentate ligand A, 1:1:2 for the tridentate ligand B, and 3:1:2 for the monodentate tri-Bu phosphate. These observed stoichiometries correlate with the number of available binding sites on each ligand as well as with potential steric effects. Energy-variable collisionally activated dissociation experiments showed that for the 2:1:2 complexes involving ligand A or B, as the ionic radius of the bound metal decreased, the removal of nitric acid required less energy and resulted in less extensive spontaneous solvent coordination. This exptl. trend suggests that, as the ionic radius of the lanthanide ion decreases, a pair of the carbamoylmethylphosphine ligands is able to more completely solvate the bound metal ion thereby weakening the nitrate-metal interaction.

Sharma, Shikha; Ghosh, Sunil K.; Sharma, Joti N. published the artcile< Sorption of ruthenium by dipropylmethyl-2-(N,N-diisobutyl) acetamidoammonium iodide impregnated Amberlite XAD-4 resin from nitric acid medium>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is ruthenium dipropylmethyldiisobutyl acetamidoammonium iodide Amberlite impregnation nitric acid sorption.

Dipropylmethyl-2-(N,N-diisobutyl)acetamidoammonium iodide has been impregnated on Amberlite XAD-4 resin and investigated for sorption of Ru from nitric acid medium. Equilibrium sorption data for Ru uptake were represented well by the Langmuir isotherm equation (R2 = 0.98) compared to Freundlich isotherm equation (R2 = 0.86). The maximum monolayer coverage (Q0) value of 6.25 mg/g as obtained from Langmuir isotherm was close to the exptl. value (5.63 mg/g). The heterogeneity parameter (1/n) = 0.37 obtained from the slope of Freundlich isotherm indicates slight heterogeneity in sorption process. Aqueous solutions of 5% ammonia or 10% sodium hydroxide were found suitable for desorption. The method can be applied for separation of Ru from acidic waste solutions

Raut, Dhaval R.; Sharma, Shikha; Ghosh, Sunil K.; Mohapatra, Prasanta K. published the artcile< Glycolamide-functionalized ionic liquid: Synthesis and actinide ion extraction studies>, Related Products of 5326-82-9, the main research area is glycolamide ionic liquid fission product actinide ion extraction enthalpy.

A glycolamide-functionalized ionic liquid (G-FIL) was synthesized for the first time and was evaluated for the extraction of actinide ions such as Am3+, Pu4+ and UO22+ and fission product element ions such as Eu3+, Sr2+ and Cs+. The extraction of the trivalent metal ions was found to be exceptionally high at low acid concentrations, which rapidly decreased with increasing acidity. In view of the high viscosity of the G-FIL, the studies were carried out using its diluted solution in a com. ionic liquid, viz. 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C4mim][Tf2N]).

Sangamides are amide derivatives of sanglifehrin A, a cyclophilin-binding polyketide natural product which is structurally distinct from cyclosporine A. Cyclosporine A is the starting point for the synthesis of cyclophilin inhibitors such as alisporivir, currently in development for the treatment of HCV infection. We report here initial results of the optimization program which led to identification of the sangamides, compounds that exhibit significantly improved potential for the treatment of chronic HCV infection.
