Lower rim substituted p-tert-butyl-calix[4]arene. Part 17. Synthesis, extractive and ionophoric properties of p-tert-butylcalix[4]arene appended with hydroxamic acid moieties
The synthesis and characterization of four p-tert-butylcalix[4]arene-hydroxamic acids are reported. The dependence of the metal ion binding, assessed by liquid–liquid extraction of the metal nitrates from water into dichloromethane in individual and competitive experiments, on the ligand structure, is presented. The results showed that those ligands could be successfully used in separation proc...
متن کاملDichloridobis[(1S,1S′,2R,2R′)-(+)-1,1′-di-tert-butyl-2,2′-diphospholane-κ2 P,P′]ruthenium(II)
In the title compound, [RuCl(2)(C(16)H(32)P(2))(2)], the Ru(II) ion is situated on a twofold rotation axis, so the asymmetric unit contains one half-mol-ecule. The slightly distorted octa-hedral environment of the Ru center is formed by four P atoms [Ru-P = 2.4417 (6) and 2.4544 (6) Å] from two different (1S,1S',2R,2R')-TangPhos ligands [(1S,1S',2R,2R')-TangPhos = (1S,1S',2R,2R')-(+)-1,1'-di-te...
متن کاملOxygen–oxygen bond dissociation enthalpies of di-tert-butyl peroxide and di-trifluoromethyl peroxide
The oxygen–oxygen bond dissociation enthalpies in di-tert-butyl peroxide (Me3CO–OCMe3) and di-trifluoromethyl peroxide (F3CO– OCF3) were determined using MP2, the hybrid functional B3LYP, and the CBS-QB3 method. Comparison of the performances of these methods, with particular emphasis on extrapolation procedures to infinite basis-set, showed that only CBS-QB3 is suitable for the accurate calcul...
متن کاملDynamics in miscible blends of polyisoprene and poly(p-tert-butyl styrene): thermorheological behavior of components
For miscible blends of moderately entangled cis-polyisoprene (PI) and poly(p-tert-butyl styrene) (PtBS), viscoelastic and dielectric properties were examined over a wide range of temperature (T ) to discuss the thermo–rheological behavior of respective components. Because PI has the type-A dipole, whereas PtBS does not, the slow dielectric response of the blends was exclusively attributed to th...
متن کاملAlkali metal ion select ability of di-propoxy- p-tert-butyl-Calix[4]arene, synthesized in acetonitrile
Synthesis and cation selectivity of 25, 27, dipropoxy-26, 28, Di-propoxy 5, 11, 17, 23, ptert-butyl Calix[4]arene are studied in acetonitrile solution. The stability constants of differentcomplexes of Calixarene (as a ligand) with alkali metal cations are determined at 25 °C by usingspectrophotometric technique.On the basis of calculations, complexation of Calixarene with Cs+and Li+ are more fa...
