Using three different approaches, racemic 1-(perfluoroalkyl)ethylamines were synthesized from perfluoroalkyl iodides or perfluoroalkanoic acids, and further transformed to the corresponding N,N'-disubstituted ethane-1,2-diimines and ethane-1,2-diamines as mixtures of diastereoisomers. Their cyclization afforded imidazolium or dihydroimidazolium salts, which led to silver or palladium complexes ...

2-Chloropyridine was used as the starting material for the preparation of 2-phenoxypyridine and 2-(4methyl)phenoxypyridine. Fluorescence studies were carried out in various solvents, capped and uncapped condition at room temperature. The fluorescence study of the above compounds with respect to time was also carried out. 2-Phenoxypyridine showed the highest fluorescence peak in methanol. The fl...

A series of novel benzimidazolium salts (1-4) and their pyridine enhanced precatalyst preparation stabilization and initiation (PEPPSI) themed palladium N-heterocyclic carbene complexes [PdCl2(NHC)(Py)] (5-8), where NHC = 1-(N-methylphthalimide)-3-alkylbenzimidazolin-2-ylidene and Py = 3-chloropyridine, were synthesized and characterized by means of (1)H and (13)C{(1)H} NMR, UV-vis (for 5-8), E...

b a ckground: type  2  diabetes  (t2d)  is  an  increasing  public  health  problem primarily because of increase in the prevalence of a sedentary lifestyle and obesity. the aim of this study was to evaluate the efficacy of self-management education on metabolic control in adults with t2d. m ethods : in a quasi-experimental study, 300 patients with t2d recruited from the diabetes society of nat...

To develop efficient materials with enhanced adsorption and selectivity for genotoxic 2-aminopyridine in water, based on magnetic chitosan (CTs) and β-cyclodextrin (β-CD), the magnetic molecularly imprinted polymers (MMIPs) of Fe₃O₄-CTs@MIP and Fe₃O₄-MAH-β-CD@MIP were synthesized by a molecular imprinting technique using 2-aminopyridine as a template. The selective adsorption experiments for 2-...

ABSTRACT A series of novel heterocyclic sulfonyl-carboximidamides were synthesized in satisfactory yields via condensation of heterocyclic methyl carbimidates with 2-chlorobenzenesulfonamide and 4-chloropyridine-3-sulfonamide. New structures were confirmed by IR and NMR spectra as well as elemental analyses. X-ray crystallography of two derivatives was performed. The single-crystal structures c...
