Chloroform extraction of nickel(II)-xanthate complexes

Synthesis, characterization, and luminescent properties of dinuclear gold(I) xanthate complexes: X-ray structure of [Au2(nBu-xanthate)2].

The synthesis and characterization of gold(I) complexes of butyl xanthate [Au(2)((n)()Bu-xanthate)(2)], 1, and ethyl xanthate [Au(2)(Et-xanthate)(2)], 2, are described. These complexes are readily prepared from the reaction between Au(THT)Cl (THT = tetrahydrothiophene) and the corresponding xanthate ligands as the potassium salts. The two xanthate complexes are characterized by (1)H NMR, IR, ma...

Synthesis, Characterization and in Vitro Antimicrobial Screening of the Xanthate Derivatives and their Iron(II) Complexes

Seven reported xanthate ligands and their new Fe(II) complexes of formulaNa[Fe(R-OCSS)3], where R is ethyl-, propyl-, butyl-, pentyl-, Hexyl-, heptyl- and octyl-xanthate have been synthesized. They have been characterized using elemental analysis, molar conductance, FT-IR, UV-Vis and 1H NMR spectroscopic techniques and melting-, decomposition-points for ligand...

Determination of free and total cholesterol by direct chloroform extraction.

Since the Liebermann-Burchard reaction was adopted by Grigaut (1) for the quantitative determination of serum total cholesterol, many modified procedures of the original method have been made. The various procedures have differed in extraction method and in the reagents used in the color development. The separation of cholesterol from its esters with digitonin has had limited application becaus...

Chloroform

It was perhaps fitting that Lieut.-Colonel Edward Lawrie, should signalise the year of his retirement from the post of R,esidenc\r Surgeon at Hyderabad by the publication of a volume on Chloroform, a subject with which he has been identified for many years past, and in defence of his views on which, and those of his master Syme, he has fought non sine gloria for many }7ears. The introduction to...
