A solid extraction process for selectively removing nitrogen from alternative refinery feedstock has been developed. It has been demonstrated that solid CuCl2 · xH2O can reduce the nitrogen content of shale oils to acceptable levels for some refiner

A novel mode of complexation of aromatics has been observed in the case of copper(I) triflate. Further, it has been found that in the solid the spatial demands of the inorganic matrix dictates a unique stability ordering of the alkylaromatics based o

Electronic excitation of solutions of the THF adduct of uranyl hexafluoroacetylacetonate results in production of a U/sup 4 +/ product. Spectral and wet-chemical analyses suggest it is U((CF/sub 3/CO)/sub 2/CH)/sub 4/. It is proposed that it occurs t

The chelated uranylhexafluoroacetylacetonate ion forms adducts with Lewis bases which are fluxional when studied by /sup 19/F NMR. The compounds have a pentagonal-bipyramidal geometry in which the base occupies one site in the equatorial ring. The ki

The THF adduct of uranyl hexafluoroacetylacetonate undergoes fast reversible displacement reactions with other bases in chloroform solutions. The NMR shift of the ..cap alpha..-CH/sub 2/ group is found to be a useful monitor of the equilibrium establ

The syntheses of p-terphenylphosphonic acid and p,p″-terphenyl-bis-phosphonic acid have been developed, and the resulting products were used to prepare layered Th(IV) and Zr(IV) phosphonates. The monoacidic terphenyl species formed a bilayered stru

By use of nonhydroxylic solvents, the series of disulfides of the tetravalent transition metals of the left side of the periodic table are preparable via a simple metathetical reaction: TX/sub 4/ + 2A/sub 2/S ..-->.. TS/sub 2/ + 4AX. The crystallinit

n -Butyllithium in hexane solution serves as an excellent reagent to effect the intercalation of lithium into the Group IVb and Vb layered dichalcogenides. Under mild conditions, highly crystalline, uncontaminated stoichiometric products are afforded
