Pyridine-type complexes of transition-metal halides XIV. Part III. Complexes with 2,4-, 2,6-, 3,4- and 3,5-lutidines

Compounds obtained by a solid-gas phase reactions between copper(II) chloride and bromide and 2,4-, 2,6-, 3,4- and 3,5-lutidines were studied using thermogravimetry, far-infrared, electronic spectroscopy and X-ray diffraction. The results were compared with the corresponding data for the similar compounds with methylpyridines and 2,4,6-collidine. A special attention was paid to the host-guest phenomenon, a new structural feature of transition-metal halide complexes.

[Zn{SSi(OBut)3}2(NH3)]2 (1) reacts with 2-picoline or 2,4-lutidine (L) without elimination of ammonia giving stable monometallic complexes [Zn{SSi(OBut)3}2(NH3)L] (3 and 4), with two different nitrogen ligands bonded to the metal center. Reaction of (ButO)3SiSH with zinc di(acetylacetonate) in ammonia atmosphere leads to the complex with two ammine ligands [Zn{SSi(OBut)3}2(NH3)2] ¡¤ MeCN (5). Molecular and crystal structures of 3, 4 and 5 have been determined by the single crystal X-ray structural analysis. All have distorted tetrahedral geometry.

A novel water-soluble highly selective ?switch-on? ionic liquid-based fluorescent chemi-sensor for Ca(II)

A novel chemi-sensor involve new bis-ionic Schiff base sensor (BISBS), N,N?-bis-[5-((2,4-lutidiniumchloride)methylene)-3-methoxysalicylidene]-R,R-1,2-cyclohexanediimine, has been synthesized and characterized. BISBS chemi-sensor was designed based on internal charge transfer (ICT) fluorescence mechanism. This new water soluble chemi-sensor provides great selectivity fluorescence detection for Ca(II) ions in an important physiological pH range. Moreover, the interaction of Ca(II) with the deprotonated BISBS to produce a metal-ligand complex with a ratio of (1: 1) accompanying with an enhancement in the intensity of emission band located at 502?nm. Fluorescence switching-on during the chemical interaction between BISBS and Ca(II) ions is very easily noticed with naked eye, but other metal cations such as alkali, alkaline earth and transition metal don’t give any fluorescence changes. The novel developed BISBS sensor successively offers low limit of detection (LOD) 1.5?nM and fast tracing of Ca(II) in the physiological pH?7.6. Thus BISBS may provide a novel auspicious methodology for detection calcium cations in the environmental and biological samples.

Multi-functional application of Moringa oleifera Lam. in nutrition and animal food products: A review

Research on the use of various parts of the Moringa oleifera Lam. plant (M. oleifera) as a nutritional and neutraceutical resource for human and animal diets has increased in recent years, emanating from the widespread use of the plant in traditional cuisines and medicinal remedies in several regions of the world. Analytical studies have identified M. oleifera as an important source of essential nutrients; rich in protein, essential amino acids, minerals, and vitamins, with a relatively low amount of antinutrients. It is also a rich source of other bio active compounds including flavonoids and phenolic compounds; with several studies detailing demonstrated in vitro and in vivo functional properties, most substantially, antioxidant activities. Moringa oleifera consumption has been reported to improve the health status, feed conversion efficiency, growth performance and product quality of several livestock species, at dietary inclusion rates generally not exceeding 5% of total dry matter intake. Fortification of processed foods with M. oleifera has been reported to increase nutritional value, some organoleptic properties, oxidative stability and product shelf life; with a notable need for further analytical and consumer studies in the development of these products. There is a paucity of literature detailing clinical studies, nutrient bioavailability, toxicity and the mode of action of the bioactive compounds to which the health claims associated with M. oleifera consumption are attributed. Many of these are not yet fully understood; therefore more research in these areas is required in order to fully utilize the potential benefits of this plant in human and livestock nutrition.

Catalytic Reactions of Pyridines. V. Alkylation of alpha-, beta-, and gamma-Picolines with Alcohols catalyzed by Ammonium Halides

A new method was found for the homogeneous liquid-phase alkylation of alpha-, beta-, and gamma-picolines with either methanol or ethanol.Addition of a catalytic amount of an ammonium halide to a mixture of a picoline and an alcohol resulted in a great increase in the yields of both side-chain and alpha-alkylated derivatives of the starting picoline when the reaction was carried out at 320-335 deg C in an atmosphere of nitrogen.The higher the reaction temperature, the greater the yields of side-chain alkylated derivatives became.In practice, this alkylation gave 2-ethylpyridine, and 2,6-lutidine from alpha-picoline with methanol, 3-ethylpyridine and 2,5-lutidine from beta-picoline from methanol, 4-ethylpyridine and 2,4-lutidine from gamma-picoline with methanol, 2-propylpyridine and 2-ethyl-6-methylpyridine from alpha-picoline with ethanol, 2-ethyl-5-methylpyridine from beta-picoline with ethanol, and 4-propylpyridine and 2-ethyl-4-methylpyridine from gamma-picoline with ethanol.Keywords-alkylation; catalyst; ammonium halide; alpha-picoline; beta-picoline; gamma-picoline; ethylpyridine; propylpyridine; methanol; ethanol
