TL;DR: In this paper, the complex permittivity spectra of amides formamide, N-methylformamide and N-dimethylformamide, as well as dipolar aprotic solvents acetonitrile, propylene carbonate and dimethylsulfoxide were determined in the frequency range 0.95-89 GHz.

TL;DR: The previously unknown titanium(IV)-containing mu-hydroxo dimeric heteropolytungstate (Bu4N)7[(PTiW11O39)2-OH] (TBA salt of H1) has been synthesized and shows higher catalytic activity than 2 for thioether oxidation by hydrogen peroxide in acetonitrile.
Abstract: The previously unknown titanium(IV)-containing μ-hydroxo dimeric heteropolytungstate (Bu4N)7[(PTiW11O39)2OH] (TBA salt of H1) has been synthesized, starting from H5PTiW11O40, and characterized by elemental analysis, multinuclear (31P, 17O, 183W) NMR, IR, FAB-MS, cyclic voltammetry, and potentiometric titration. 31P NMR reveals that H1 (δ −12.76) readily forms in MeCN from the Keggin monomer (POM), PTiW11O405- (2, δ −13.34), upon the addition of 1.5 equiv of H+, via the protonated species, P(TiOH)W11O394- (H2, δ −13.44). The ratio of H1, 2, and H2, which are present in equilibrium in MeCN solution at 25 °C, depends on the concentration of both H+ and H2O. The Ti−O−Ti linkage readily reacts with nucleophilic reagents, such as H2O and ROH, to yield monomeric Keggin derivatives. μ-Hydroxo dimer H1 shows higher catalytic activity than 2 for thioether oxidation by hydrogen peroxide in acetonitrile. The reaction proceeds readily at room temperature and affords the corresponding sulfoxide and sulfone in ca. quant...
