(208-209)Naphthol-Dyes and its Intermediates IV-V

Vanadium (IV and V) speciation with a catechol derivative and tetrazolium salt

The possibility of application of 4-nitrocatechol (4-NC) - tetrazolium salt - organic solventsystems for liquid-liquid extraction-spectrophotometric vanadium (IV and V) speciation wasstudied. Six commercially available tetrazolium salts (2,3,5-triphenyltetrazolium chloride (TTC),3-(2-naphtyl)-2,5-diphenyltetrazolium chloride (Tetrazolium Violet, TV); 3-(4,5-dimethyl-2-thiazol)-2,5-diphenyltetra...

Trapping five-coordinate platinum(iv) intermediates.

The oxidation of three different complexes of the doubly cycloplatinated 2,6-di(4-fluorophenyl)pyridine ligand (namely DMSO, PPh3 and PPr3 derivatives, 1a, 1b and 1c, respectively) with the electrophilic oxidant iodobenzenedichloride was studied. In each case oxidation can yield a simple trans-dichloro platinum(iv) complex (2(t)), which subsequently isomerises to the cis isomer (2(c)). However,...

Rvx 208

RVX 208 (RVX-208; RVX000222) is a first-in-class novel small molecule in development by Resverlogix Corporation for acute coronary syndromes, atherosclerosis and Alzheimer disease. It increases the levels of apolipoprotein A1 and high-density lipoprotein cholesterol, thereby potentially reducing the risk for cardiovascular disease. This review discusses the key development milestones and therap...

Eco-Friendly Synthesis of Some Thiosemicarbazones and Their Applications as Intermediates for 5-Arylazothiazole Disperse Dyes.

The solid-solid reactions of thiosemicarbazide with 4-formylantipyrine, 2-acetylpyrrole and camphor were performed to afford the thiosemicarbazones 1-3 which underwent hetero-cyclization with phenacyl bromide to furnish the corresponding thiazole derivatives 4-6. The yields of the reactions are quantitative in all cases and the products do not require further purification. A series of 5-arylazo...
